Resumo: O enfrentamento da pandemia de Covid-19 exige que o Estado tome decisões difíceis que perpassam a ação da burocracia que implementa políticas públicas na interação com a população, a burocracia de nível de rua (BNR). Neste artigo, baseado em estudo exploratório de método misto, analisamos como a atuação cotidiana desses burocratas em diferentes políticas públicas - saúde, assistência social, acesso à justiça, segurança pública e educação - foi alterada durante a pandemia, bem como analisamos as suas consequências. Três categorias que ilustram a dinâmica do trabalho da BNR durante a pandemia foram identificadas por análise dos sentimentos dos burocratas, mudanças no seu trabalho e na relação com a população: a BNR que enfrenta a crise na linha de frente; a BNR que sofre os efeitos da pandemia, mas cujo trabalho não demanda enfrentá-la diretamente; e a BNR cujo trabalho migrou para o formato remoto. Concluímos que, durante a pandemia, a BNR, em diferentes graus, deparou-se com um agravamento de problemas estruturais, como o seu alijamento dos processos decisórios, restritos ao alto escalão governamental, e a exacerbação de conflitos e ambiguidades já existentes.

Abstract: Dealing with the Covid-19 pandemic requires that the State make hard decisions that involve the action of bureaucrats who interact with the population through the implementation of public policy, the street-level bureaucracy (SLB). In this paper, based on a mixed- method exploratory study, we analyze how the daily performance of street-level bureaucrats in different policy areas- health and social care, access to the justice system, public security and education - has changed during the pandemic. We also explore the repercussions of those changes. Based on the analysis of the perceptions of bureaucrats, changes in their work and in their relationship with the public, we identify three categories that illustrate the dynamics of SLB work during the pandemic: the SLB who faces the crisis on the front lines; the SLB who suffers the effects of the pandemic, but whose work does not require her to face it directly; and the SLB who began to work remotely. We conclude that, during the pandemic, SLB suffered in varying degrees an aggravation of structural problems, such as their removal from decision-making processes - now restricted to the highest government level - and the exacerbation of already existing conflicts and ambiguities.

Resumen: Hacer frente a la pandemia de Covid-19 requiere que el Estado tome decisiones difíciles que van más allá de la acción de la burocracia que implementa las políticas públicas en la interacción con la población, la burocracia de primera línea (BPL). En este artículo, a partir de un estudio exploratorio de método mixto, analizamos cómo el desempeño diario de estos burócratas en diferentes políticas públicas - salud, asistencia social, acceso a la justicia, seguridad pública y educación - se modificó durante la pandemia y sus consecuencias. Se identificaron tres categorías que ilustran la dinámica del trabajo de BNR durante la pandemia, analizando los sentimientos de los burócratas, los cambios en su trabajo y en la relación con la población: la BPL que enfrenta la crisis en primera línea; la BPL que sufre los efectos de la pandemia, pero cuyo trabajo no exige enfrentarla directamente; y la BPL cuyo trabajo migró al formato remoto. Concluimos que, durante la pandemia, la BPL, en diferentes grados, enfrentó un agravamiento de problemas estructurales, como su remoción de los procesos de toma de decisiones, restringida al más alto nivel de gobierno, y la exacerbación de conflictos y ambigüedades ya existentes.

RESUMO: A mastite é um problema sanitário importante em ovelhas da raça Santa Inês, ocasionando prejuízo ao produtor em virtude do descarte de matrizes e da queda no ganho de peso dos cordeiros. O objetivo deste trabalho foi avaliar a saúde da glândula mamária de ovelhas da raça Santa Inês na secagem e no puerpério e pesquisar a eficácia da terapia intramamária com gentamicina na secagem. Sessenta e quatro ovelhas foram divididas em grupos controle (GC) e tratamento (GT), cada um contendo 32 animais, e a saúde da glândula mamária avaliada na secagem e no puerpério. As ovelhas do GT receberam 250mg de gentamicina (Gentocin® Mastite Vaca Seca/ Schering-Plough Veterinária, produto indicado pela empresa para utilização em vacas de leite) em cada metade mamária. Para o diagnóstico, foram realizados exame físico da glândula mamária, California Mastitis Test, contagem de células somáticas e cultura do leite. No GC, das 45 (70,3%) metades mamárias sadias na secagem, 12 desenvolveram mastite subclínica e nove mastite clínica no puerpério. No GT, das 51 (79,7%) metades mamárias sadias na secagem, seis desenvolveram mastite subclínica e 11 mastite clínica no puerpério. Não houve associação entre o tratamento e a ocorrência de mastite no puerpério. Das 19 (29,7%) metades mamárias do GC que apresentaram mastite subclínica na secagem, três permaneceram com mastite subclínica e cinco desenvolveram mastite clínica no puerpério. No GT, das 13 (20,3%) metades mamárias com mastite subclínica na secagem, quatro permaneceram com mastite subclínica e quatro desenvolveram mastite clínica. Não houve associação entre o tratamento e a cura ou persistência da mastite no puerpério. Os principais micro-organismos isolados, na secagem e puerpério, de animais com mastite subclínica ou clínica foram Staphylococcus spp., com predominância de Staphylococcus Coagulase Negativa (SCN). No puerpério, ocorreram 29 casos de mastite clínica, sendo 19 com isolamento, 10 com SCN e seis com S. aureus. Mannheimia haemolytica foi isolado em um caso de mastite subclínica e um caso de mastite clínica. Novos protocolos e diferentes formas de manejo na secagem e no puerpério devem ser pesquisados

ABSTRACT: Mastitis represents an important health problem for Santa Inês breed, causing losses to the producer, due to loss of ewes or the decrease in weight gain of lambs. The aim of this work was to assess the health of the mammary gland of Santa Inês ewes at the drying and puerperium and to investigate the efficacy of a dry-off therapy with gentamicin. In this study, 64 ewes were divided in a control group (GC) and treatment group (GT), and the health of the mammary gland was assessed at the drying and puerperium. The GT ewes received 250mg of gentamicin (Gentocin® DryCow/Schering-Plough, product indicated for use in dairy cows) in each mammary half. For diagnosis, clinical examination, California Mastitis Test, somatic cell count and milk culture was performed. In the GC, of the 45 (70.3%) healthy mammary halves at the drying, 12 developed subclinical mastitis and nine clinical mastitis at the puerperium. In the GT, among 51 (79.7%) healthy mammary halves at the drying, six developed subclinical mastitis and 11 clinical mastitis at the puerperium. No association was observed between treatment and the occurrence of mastitis at puerperium. Of the 19 (29.7%) mammary halves of the GC that presented subclinical mastitis at the drying, three remained with subclinical mastitis and five developed clinical mastitis at the puerperium. In the GT, of the 13 (20.3%) mammary halves that had subclinical mastitis at the drying, four remained with subclinical mastitis and four developed clinical mastitis. No association was observed between treatment and cure or persistence of mastitis at the puerperium. The main microorganisms isolated, at the drying and puerperium, from animals with subclinical or clinical mastitis were Staphylococcus spp., predominantly coagulase negative Staphylococcus (CSN). At the puerperium, 29 cases of clinical mastitis occurred, 19 with isolation, where 10 were CNS and six S. aureus. Mannheimia haemolytica was isolated in one case of subclinical mastitis and other of clinical mastitis. News protocols and different ways of handling at drying and at puerperium must be investigated.

Abstract Histophilus somni is a Gram-negative bacterium that is associated with a disease complex (termed histophilosis) that can produce several clinical syndromes predominantly in cattle, but also in sheep. Histophilosis is well described in North America, Canada, and in some European countries. In Brazil, histophilosis has been described in cattle with respiratory, reproductive, and systemic disease, with only one case described in sheep. This report describes the occurrence of Histophilus somni-associated disease in sheep from Southern Brazil. Eight sheep with different clinical manifestations from five farms were investigated by a combination of pathological and molecular diagnostic methods to identify additional cases of histophilosis in sheep from Brazil. The principal pathological lesions were thrombotic meningoencephalitis, fibrinous bronchopneumonia, pulmonary abscesses, and necrotizing myocarditis. The main clinical syndromes associated with H. somni were thrombotic meningoencephalitis (n = 4), septicemia (n = 4), bronchopneumonia (n = 4), and myocarditis (n = 3). H. somni DNA was amplified from multiple tissues of all sheep with clinical syndromes of histophilosis; sequencing confirmed the PCR results. Further, PCR assays to detect Pasteurella multocida and Mannheimia haemolytica were negative. These findings confirmed the participation of H. somni in the clinical syndromes investigated during this study, and adds to the previous report of histophilosis in sheep from Brazil.

RESUMO O objetivo com este estudo foi avaliar a utilização de silagens de diferentes cultivares de sorgo através do consumo, digestibilidade dos nutrientes e desempenho de ovinos. O experimento foi conduzido na Estação Experimental de Pendência, da Empresa Estadual de Pesquisa Agropecuária da Paraíba S.A. Para o experimento, foram utilizados trinta e cinco carneiros, sem raça definida, com peso vivo médio de 17,7 kg, distribuídos em um delineamento em blocos casualizados, com cinco tratamentos e sete repetições para determinar o consumo e desempenho; e 25 carneiros não castrados, sem raça definida, distribuídos em um delineamento inteiramente casualizado, com cinco tratamentos e cinco repetições, para determinar a digestibilidade dos nutrientes. O consumo médio diário de matéria seca foi, em média, 994,66 g. Somente os consumos médios de extrato etéreo, fibra em detergente neutro e carboidratos não-fibrosos, foram afetados pelas dietas. O ganho de peso (GP), conversão alimentar e eficiência alimentar dos animais que receberam as dietas não foram afetados pelos diferentes cultivares utilizados. Silagens de sorgo BRS 655, 610, 800, 810 e Ponta Negra promoveram consumo e digestibilidade de nutrientes semelhantes. A utilização de silagens de diferentes cultivares de sorgo (BRS 610, BRS 655, BRS 800, BRS 810 e Ponta Negra) em dietas para ovinos em confinamento promove desempenho e consumo similar.

SUMMARY The aim of this study was to evaluate the use of silages of different sorghum cultivars through digestibility and nutrient intake and performance of sheep. The experiment was conducted at the Pendência Experimental Station, of the State Company for Agricultural Research of Paraíba S.A. For the experiment, thirty-five rams were used, without defined breed, with average live weight of 17.7 kg, distributed in a completely randomized block design, with five diets and seven replicates to determine intake and performance; and 25 non-castrated rams, without defined breed, distributed in a completely randomized design with five diets and five replicates, to determine the digestibility of nutrients. The average daily intake of dry matter was, on average, 994.66 g. Only the average intakes of ether extract, neutral detergent fiber and non-fibrous carbohydrates, were affected by the diets. The weight gain (WG), feed conversion and feed efficiency of the animals receiving the diets suffered no effect. Silages of BRS 655, 610, 800, 810 and Ponta Negra provided similar intake and digestibility of nutrients. The use of silages of different sorghum cultivars (BRS 610, BRS 655, BRS 800, BRS 810 and Ponta Negra) in diets for confined sheep provide similar performance and intakes.

Neste trabalho descrevemos a preparação e a caracterização espectroscópica [ressonância paramagnética eletrônica (EPR), espectroscopia UV-Vis e espectroscopia de infravermelho com transformada de Fourier (FTIR)], magnética e espectroeletroquímica do complexo [MnII2(tidf)(OAc)(ClO4)(MeOH)] (tidf = ligante macrocíclico do tipo Robson, obtido pela condensação entre 2,6-diformil-4-metilfenol e 1,3-diaminopropano). O composto [MnII2(tidf)(OAc)(ClO4)(MeOH)] exibe antiferromagnetismo fraco e constante de acoplamento magnético J = -1.59(1) cm-1. A oxidação de [MnII2(tidf)(OAc)(ClO4)(MeOH)] monitorada por experimentos de espectroeletroquímica de UV-Vis e de EPR produziu espécies de valência mista Mn2(II/III) com perfil espectral semelhante ao do complexo [MnII MnIII(tidf)Br3(H2O)2]. Tentativas de cristalização de [MnII2(tidf)(OAc)(ClO4)(MeOH)] produziram o complexo trinuclear de manganês [Mn3III/II/III(tidf)2(µ-OAc)2](ClO4)2. O composto possui duas unidades [MnIII(tidf)]+ onde o íon metálico é pentacoordenado e conectadas a um íon central de MnII hexacoordenado através de pontes µ-fenolato e µ-acetato.

Synthesis, spectroscopic [electron paramagnetic resonance (EPR), UV-Vis and Fourier transform infrared spectroscopy (FTIR)], magnetic and spectroeletrochemical properties of [MnII2(tidf)(OAc)(ClO4)(MeOH)] (tidf = a Robson type macrocyclic ligand obtained through condensation of 2,6-diformyl-4-methylphenol and 1,3-diaminopropane) are reported. Compound [MnII2(tidf)(OAc)(ClO4)(MeOH)] shows a weak antiferromagnetic behavior with exchange coupling constant J = -1.59(1) cm-1. UV-Vis and EPR spectroelectrochemical response after oxidation of complex [MnII2(tidf)(OAc)(ClO4)(MeOH)] detected the stabilization of mixed-valence Mn2(II/III) species in solution showing spectral features similar to the ones of the isolated mixedvalence [MnII MnIII(tidf)Br3(H2O)2] compound. Crystallization of [MnII2(tidf)(OAc)(ClO4)(MeOH)] surprisingly produced the trimanganese complex [Mn3III/II/III(tidf)2(µ-OAc)2](ClO4)2, not observed in solution. It contains two pentacoordinated [MnIII(tidf)]+ units, each one connected to a central hexacoordinated MnII ion through one µ-phenolate and one µ-acetate bridge.

Toxic compounds in sewage or industrial wastewater may inhibit the biological activity of activated sludge impairing the treatment process. This paper evaluates the Inhibition Capacity Index (ICI) for the assessment of activated sludge in the presence of toxicants. In this study, activated sludge was obtained from industrial treatment plants and was also synthetically produced. Continuous respirometric measurements were carried out in a reactor, and the oxygen uptake rate profile obtained was used to evaluate the impact of inhibiting toxicants, such as dissolved copper, phenol, sodium alkylbenzene sulfonate and amoxicillin, on activated sludge. The results indicate that ICI is an efficient tool to quantify the intoxication capacity. The activated sludge from the pharmaceutical industry showed higher resistance than the sludge from other sources, since toxicants are widely discharged in the biological treatment system. The ICI range was from 58 to 81% when compared to the synthetic effluent with no toxic substances.

A mastite em ovelhas da raça Santa Inês apresenta-se como um problema de grande proporção e gravidade e é dificilmente tratada com sucesso. O objetivo deste estudo foi caracterizar aspectos clínicos, epidemiológicos e etiológicos da mastite clínica em ovelhas de corte criadas no norte do Paraná. O presente estudo foi realizado entre os meses de outubro de 2009 a setembro de 2010 envolvendo 54 rebanhos de ovinos de corte de diferentes raças. Durante as visitas às propriedades, um questionário foi preenchido com a finalidade de caracterizar o problema. Setenta ovelhas com mastite clínica foram examinadas e amostras de secreção láctea foram colhidas para exame microbiológico. A mastite foi considerada um problema relevante em 39 propriedades (72,3%), com frequência média de 6,74%. Casos crônicos e agudos de mastite foram observados em 69% e 31% das ovelhas examinadas, respectivamente. Em ambos os casos, a mastite flegmonosa foi a forma mais encontrada (65,5% dos casos). O agente etiológico mais prevalente foi Staphylococcus coagulase negativo (54,5%), seguido por S. aureus e A. pyogenes (11,5% cada). Mannheimia haemolytica foi isolada em dois casos. Sistema de criação não extensivo e raça Santa Inês foram identificados como fatores de risco para o desenvolvimento de mastite clínica. Secagem das fêmeas após 120 dias de lactação e separação de fêmeas doentes do rebanho foram associadas com menor ocorrência da doença. Recomenda-se a limpeza adequada das instalações e a secagem mais tardia, principalmente em rebanhos Santa Inês.

Mastits is infrequent in meat ewes. However Santa Ines ewes have a high incidence of this disease and it is severe and difficult to treat. The goal of this study was to characterize clinical, epidemiological and etiological aspects of clinical mastitis in meat ewes reared in the north of Parana, Brazil. Fifith four farms were visited from October 2009 to September 2010. The surveyed data included frequency, breeds of sheep affected, lamb mortality rates, main clinical signs, attempts and outcome of treatment, method and period of weaning and management features. Seventy ewes with clinical mastitis were fully examinated and samples of mammary secretion were asseptically taken for bacteriological culture. Mastitis was identified in 39 farms (72.3%) as a relevant problem (mean frequency was 6,74%). Chronic and acute mastitis were observed in 69% and 31% of the examinated ewes, respectively. In both cases, phlegmonous mastitis was the most prevalent form (65.5%). Coagulase negative Staphylococccus (CNS) was the main isolated microorganism (54.5%), followed by Staphylococcus aureus and Arcanobacterium pyogenes (11.5%, each one). Mannheimia haemolytica was found in two cases. The risk factors for clinical mastitis were intensive management system and Santa Ines breed. Weaning after 120 days of lactation and isolation of affected ewes were associated with lower frequency of mastitis. Preventive measures recommended are daily cleaning of facilities and delayed weaning, mainly in Santa Ines flocks.

This work presents a kinetic study of the enzymatic hydrolysis of three cellulosic substrates: filter paper (FP), used as a low recalcitrance substrate model; steam exploded sugarcane bagasse (SB); and weak acid pretreated SB (1:20 dry bagasse:H2SO4 solution 1% w/w), the last two delignified with 4% NaOH (w/w). The influence of substrate concentration was assessed in hydrolysis experiments in a shaker, using Accellerase® 1500, at pH 4.8, in 50 mM sodium citrate buffer. Cellulose loads (weight substrate/weight total) were changed between 0.5%-13% (for FP) and 0.99%-9.09% (for SB). For FP and low loads of steam exploded SB, it was possible to fit pseudo-homogeneous Michaelis-Menten models (with inhibition). For FP and higher loads of steam exploded SB, modified Michaelis-Menten models were fitted. Besides, it was observed that, after retuning of the model parameters, it is possible to apply a model fitted for one situation to a different case. Chrastil models were also fitted and they were the only feasible approach for the highly recalcitrant acid-treated SB.

Neste artigo eu ofereço um plano conciso acerca das edições críticas das Preleções sobre a Filosofia da Religião de Hegel enfatizando o método seguido pelos editores com o intuito de construir um texto coerente com as fontes disponíveis para eles. A edição de Marheineke (1832) é analisada com especial atenção dado que ela foi a edição que produziu a divisão entre uma Direita e uma Esquerda, bem como inaugurou a discussão sobre o teísmo especulativo como consequência da dificuldade de se distinguir a parte sistemática da histórica na argumentação desenvolvida por Hegel.

In this paper I provide a concise plan about Hegel's Lectures on the Philosophy of Religion critical editions, laying stress on the method followed by editors in order to build a coherent text with the sources at their disposal. The Marheineke's edition (1832) is analysed with special attention since it was the edition that caused the division between a Right and a Left, opening the discussion on speculative theism as a consequence of the difficulty to distinguish the systematic part from the historical one in the reasoning carried out by Hegel.

Toxic and repellent properties of whole essential oils from four Eupatorium (Asteraceae) species (E. buniifolium Hook. et Arn, E. inulaefolium Kunth, E. arnottii Baker, and E. viscidum Hook. & Arn) were investigated in different concentrations toward Tribolium castaneum Herbst adults. The essential oils were isolated by hydrodistillation techniques from the aerial parts. The analysis was performed by GC-FID and GC-MS methods. Contact toxicity assays showed that all the evaluated essential oils were toxic. Furthermore, in all the cases mortality was dose dependent. The main repellency was observed for the essential oil recovered from E. buniifolium.

Se evaluaron las propiedades tóxicas y repelentes de los aceites esenciales de cuatro especies del género Eupatorium (Asteraceae): E. buniifolium Hook. et Arn, E. inulaefolium Kunth, E. arnottii Baker y E. viscidum Hook. & Arn, en diferentes concentraciones frente a adultos de Tribolium castaneum Herbst. Los aceites esenciales se aislaron de las partes aéreas de las plantas, mediante técnicas de hidrodestilación y se analizaron por los métodos GC-FID y GC-MS. Los ensayos de toxicidad por contacto demostraron que todos los aceites fueron tóxicos y la mortalidad fue, en todos los casos, dependiente de la dosis. El aceite esencial de E. buniifolium presentó la mayor actividad repelente.

This work reports the influence of different culture preservation methods on the production of penicillin G acylase (PGA) by Bacillus megaterium ATCC 14945. The initial stock culture, presenting PGA activity of 97 IU l-1, was preserved for two years using different procedures: monthly subculturing and storage in refrigerator (S), freeze-drying using skim milk 10%, plus inositol 5% as cryoprotectors (L1), freeze-drying using sucrose 7%, plus peptone 7% (L2), and freezing with glycerol 10% (F). After cultivations at standard operational conditions, different values of enzyme activity were obtained: 56 IU l-1 for monthly subculturing (S), 15-41 IU l-1 for freeze-dried cells and frozen spores. All the tested methods have failed in preserving the PGA expression. Among all tested cultures, S presented the highest specific activity, and was used to prepare a standard inoculum in cryovials (-50ºC, frozen spores in a 20% glycerol solution). By cultivation of this inoculum under different conditions, it was found that PGA activity raised to 128 IU l-1 when 0.4 g l-1 of salts was added to the medium.

La enfermedad de Chagas sigue siendo un problema en Venezuela y en varios países de Latinoamérica. Este trabajo presenta datos sobre las alteraciones que esta enfermedad produce en los músculos esqueléticos periféricos, lo cual puede contribuir a la incapacidad funcional que presentan muchos de los pacientes. Fueron estudiados 19 pacientes con enfermedad avanzada, a quienes se les hizo evaluación cardiorrespiratoria, ecocardiograma, prueba de ejercicio y biopsia del músculo cuádriceps. El 42 % presentó incapacidad funcional moderada a severa, medida por el consumo máximo de oxígeno, que estuvo relacionada con cambios morfológicos y metabólicos en las fibras musculares. Se hallaron alteraciones en la microvasculatura muscular compatibles con daño autoinmune. En conclusión, los pacientes con enfermedad de Chagas sufren alteraciones en la musculatura periférica que puede contribuir a la incapacidad funcional y al grado de afectación por esta enfermedad. La determinación de la capacidad funcional debería agregarse a la evaluación de la enfermedad.

Chagas’ disease is still a problem in Venezuela and other Latin American countries, in spite of efforts to control the disease. Peripheral muscle alterations that contribute to decreased functional capacity in moderate to advanced Chagas’ disease patients are analyzed in the present work. Nineteen Chagas’ disease patients were studied, including cardio-respiratory evaluation, echocardiogram, exercise test and quadriceps muscle biopsy. The results showed 42 % patients with moderate to severe decrease of maximal oxygen consumption. Muscle biopsies presented morphologic and metabolic alterations, some related to functional capacity. Capillary vessel damage in muscle was similar to that found in autoimmune diseases. In conclusion, Chagas’ disease patients showed peripheral muscle alterations related to decreased functional capacity. The functional capacity changes may contribute to the severity of the disease and should be added to the evaluation of the patients.

The production of penicillin G acylase (PGA, an important industrial enzyme) from a wild strain of Bacillus megaterium using a pool of free amino acids as substrate was studied in a bench-scale bioreactor. Experiments carried out in shakers showed that the substitution of casein for free amino acids in the presence of cheese whey was the culture medium that provided the highest productivity. Several cultivations were carried out in a bioreactor operated in either batch or fed-batch mode. Batch runs showed that enzyme production is associated with microorganism growth. The following set of amino acids was preferentially consumed: Ala, Arg, Asp, Gly, Lys, Ser, Thr and Trp. On the other hand, the rates of consumption of His, Ile, Leu, Met, Phe, Pro, Tyr and Val were lower.

Penicillin G acylase (PGA) is an important enzyme used as biocatalyst in the production of semisynthetic beta-lactam antibiotics. Many microorganisms produce this enzyme and recombinant Escherichia coli has been preferred use for industrial applications. Bacillus megaterium is one of the microorganisms that excretes this enzyme into the medium. As a consequence, separation and purification steps are simplified. On-line measurement of enzyme activity during cultivation using in-situ sensors is a difficult task in the industrial environment due to the lack of robust and inexpensive instrumentation. This work presents the results of a fuzzy logic algorithm used to determine the moment of maximum enzyme concentration during Bacillus megaterium cultivations in an aerated and stirred, automated lab-scale bioreactor. The fuzzy algorithm was written in Fortran, compiled as a dynamic link library and implemented on a platform developed in MS-Visual Basic. Data were exchanged in real time between the platform and the supervisory system, which was coupled to the bioreactor. It was possible to determine the moment at which maximum enzyme activity was reached in several bioreactor assays. At this point, the end of the process was indicated to the operator. The results illustrate the importance of using reliable computational intelligence-based algorithms in biochemical reactions.
