Species from Pavonia genus (Malvaceae) are traditionally used as antioxidant, n anti inflammatory and antimicrobial remedies. Previous studies have revealed their diversity of specialized metabolites widely used in the development of new medicines. This is the first study on Pavonia glazioviana Gurke, a Brazilian species known as “Malva da Chapada”. The research led to identify fifteen compounds: 132 (S) hydroxy pheophytin a; and 132(S) hydroxy 173 ethoxyphaeophorbide, n decanol, cycloart 23Z ene 3β,25 diol, cycloart 24S 25 ene 3β,24 diol, sitosterol 3 O β D glucopyranoside, stigmasterol 3 O β D glucopyranoside, quercetin, acacetin, kaempferol, tiliroside, 5 hydroxy 3,7,8,4’ tetramethoxyflavone, 5,7 dihydroxy 3,8,4’ trimethoxyflavone, 5,7 dihydroxy 4’ methoxyflavone, 5,7,4’ trihydroxy 3,8 dimethoxyflavone and 5,7,4’ trihydroxy 3 methoxyflavone. The major flavonoids were tested for their antimicrobial activity, and the compound 5,7 dihydroxy 3,8,4’ trimethoxyflavone showed strong activity against Escherichia coli (MIC = 512 μg mL1), Pseudomonas aeruginosa (MIC = 512 μg mL1), Candida albicans (MIC = 512 μg mL1), Candida tropicalis (MIC = 512 μg mL1), Candida parapsilosis (MIC = 512 μg mL1), Aspergillus flavus (MIC = 512 μg mL1) and A. fumigantus (MIC = 512 μg mL1). The total phenolic content, flavonoid content, and radical scavenging potential were determined showing its great production of phenolics and flavonoids, along with interesting radical scavenging potential (DPPH EC50 = 6.36 ± 0.029 mg mL 1). Our findings contributed to characterize P. glazioviana as a source of methoxylated flavonoids with antimicrobial potential. Malvaceae (Malvaceae antioxidant remedies medicines Gurke Malva Chapada.

ABSTRACT Alternative techniques for cultivation without soil are widespread; however, studies comparing hydroponic systems still need to be studied, mainly in semi-arid regions. The present study aimed to evaluate the effect of hydroponic systems on the yield and quality of lettuce cultivars subjected to different electrical conductivities of the nutrient solution. The research was conducted in a greenhouse, adopting a completely randomized design in a 2 × 2 × 3 factorial scheme, being two lettuce cultivars (Cinderela and Rubinela), two electrical conductivities (2.90 and 1.6 dS m-1), and three hydroponics systems (NFT, semi-hydroponic, and floating), with three replications. The number of leaves, leaf succulence, specific leaf area, leaf fresh mass, total dry mass, leaf area, titratable acidity, vitamin C, and soluble solids were evaluated. Cinderela cultivar showed the highest average leaf fresh mass, total dry mass, leaf area, and vitamin C values. The NFT and floating systems provided the highest leaf yield and quality, especially in the solution of 1.60 dS m-1. The semi-hydroponic system provided greater development of the plants with a more concentrated nutrient solution (2.90 dS m-1). widespread however studied semiarid semi arid regions greenhouse scheme Rubinela, Rubinela , Rubinela) 2.90 290 90 (2.9 16 1 6 1. m1, m1 m m-1) NFT, (NFT semihydroponic, semihydroponic hydroponic, floating, floating) replications leaves succulence area mass acidity evaluated values 160 60 m1. m-1 . 2.9 29 9 (2. m- 2.

RESUMO: O principal anticorpo presente nas mucosas e glândulas exócrinas é uma IgA polimétrica denominada sIgA. Esta imunoglobulina vem sendo utilizada como indicadora de estresse em diversos animais incluindo primatas não humanos, podendo também ser utilizada para o monitoramento da atividade imunológica. A imunoglobulina A secretora é encontrada predominantemente em secreções seromucosas, como saliva, lágrimas, colostro, leite, liquor, bem como secreções traqueobrônquicas, intestinais e geniturinárias. O objetivo deste estudo foi mensurar os níveis da IgA salivar em Callithrix jacchus (sagui comum) através do teste de imunoabsorção enzimática (ELISA). Doze pares de animais foram previamente condicionados pela técnica de condicionamento operante com reforço positivo à coleta de saliva. As amostras foram coletadas uma vez por semana por seis meses. Neste experimento as concentrações de imunoglobulina salivar A secretora em Callithrix jacchus foram muito baixas. Nós sugerimos novos estudos utilizando outras técnicas para quantificar a IgA na saliva desses animais.

ABSTRACT: The primary antibody in the mucous membranes and exocrine glands is a polymetric secretory immunoglobulin A. This immunoglobulin has been used as an indicator of stress in various animals, including nonhuman primates, and can also be used to monitor immune activity. The secretory immunoglobulin A is predominantly found in seromucous secretions such as saliva, tears, colostrum, milk, and liquor, as well as tracheobronchial, intestinal, and genitourinary secretions. This study aimed to measure the salivary IgA levels in Callithrix jacchus (common marmoset) by the enzyme-linked immunosorbent assay test (ELISA). Twelve pairs of animals were used, previously conditioned by the operant conditioning technique with positive reinforcement to saliva collection. Samples were collected once a week for six months. In this experiment, the salivary secretory immunoglobulin A concentrations in Callithrix jacchus were very low. We suggest new studies using other techniques to quantify the IgA quantities in the saliva of these animals.

In this study, nanostructured coatings of VN2/Fe3N/Fe4N are synthesized by Plasma Deposition (CCPD) using a vanadium cathodic cage and subject to cathodic and floating potential treatments. Microstructural and mechanical properties of coated SAE 1080 steel samples are investigated using X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Vickers microhardness (HV), and surface roughness analysis. The coating produced under cathodic potential treatment exhibited a nitride-based microstructure (VN2, Fe3N, Fe4N), with surface morphology consisting of clusters of granular structures with varied particle sizes. The coating produced under floating potential predominantly exhibited the iron nitride phase (Fe3N) with a morphology composed of uniformly sized grains. Microhardness testing showed that both layers exhibited more excellent plastic deformation resistance than the substrate. Roughness measurements confirmed a more organized microstructure profile for the sample treated under floating potential. This study demonstrates that the CCPD-produced cathodic potential coating can be utilized in tribological applications.

Abstract The jabuticaba bark is rich in anthocyanins and fibers, and its use may be of industrial interest. In the food sector, its used as an ingredient in the production of fermented products, liqueurs or enriched flours. It also has pharmaceutical and cosmetic applications. The objective was to evaluate the effect of pretreatment and fresh use of jabuticaba peels in the extraction of total phenolic compound (TPC) and total anthocyanin (TA) contents with and without ultrasound assistance and in the sequential extraction of pectin from the residue. In the TPC and TA extraction, a 3x2 factorial design was used. For conventional anthocyanin extraction (CAE), occurred in an incubator under agitation. For ultrasound-assisted anthocyanin extraction (UAE) was utilized an ultrasonic homogenizer with probe (20 kHz, 160 W). The extracts were quantified (TPC, TA, antioxidant activity and color). The residues were characterized and used for sequential pectin extraction, which was quantified and characterized. The results were subjected to analysis of variance. Fresh jabuticaba peel is a residue that can be used to sequentially extract phenolic compounds, particularly anthocyanins and pectin. The use of ultrasound (UAE) was less efficient than CAE for extracting TPC and TA or performing sequential extraction on all pretreatment peels. fibers interest sector products flours applications (TPC (TA x 3x CAE, , (CAE) agitation ultrasoundassisted assisted UAE (UAE 20 (2 kHz 16 W.

RESUMO O declínio-da-goiabeira é uma doença complexa, causada por Meloidogyne enterolobii em interação com Neocosmospora falciformis (sin. Fusarium solani). Por causa disso, a seleção de genótipos resistentes a M. enterolobii dentro do gênero Psidium é muito importante para o controle da doença. A detecção desta resistência em Psidium guajava seria, ainda, de maior impacto. Assim, este trabalho teve por objetivo avaliar a reação de P. guajava ‘Paluma’ a diferentes densidades de inóculo de M. enterolobii. Mudas de goiabeira foram inoculadas com 500, 1000, 5000, 10000 e 20000 ovos + juvenis de segundo estádio (J2) de M. enterolobii/planta. Aos 70 e aos 135 dias após a inoculação (DAI), foram avaliadas as massas de matérias frescas de raiz, de parte aérea e de matéria seca de parte aérea, bem como o comprimento de raiz, a altura da planta e o diâmetro do colo. Os números totais de ovos + J2 de M. enterolobii nos sistemas radiculares e os fatores de reprodução foram as variáveis nematológicas determinadas. A multiplicação do nematoide nas raízes não foi proporcional ao aumento da densidade de inóculo inicial e, por isso, nas menores densidades, encontraram-se as melhores respostas de multiplicação do nematoide na cultivar avaliada. Observou-se, então, que, conforme se aumentou a densidade de inóculo, obtiveram-se menores fatores de reprodução médios nas duas avaliações (70 e 135 DAI). declíniodagoiabeira declínio complexa sin. sin (sin solani. solani . solani) disso M seria ainda impacto Assim P ‘Paluma Paluma 500 1000 5000 2000 J (J2 enterolobiiplanta enterolobii/planta 7 13 DAI, DAI , (DAI) raiz colo determinadas isso encontraramse encontraram avaliada Observouse, Observouse Observou se, Observou-se então que obtiveramse obtiveram (7 DAI.

ABSTRACT Guava decline is a complex disease caused by the interaction between Meloidogyne enterolobii and Neocosmospora falciformis (Syn.: Fusarium solani). Thus, selecting M. enterolobii-resistant genotypes within the genus Psidium is essential for controlling this disease, and developing a resistant cultivar of Psidium guajava could significantly impact this issue. Thus, the objective of this study was to assess the response of the guava plants of the cultivar Paluma to different densities of M. enterolobii inoculum. Guava seedlings were inoculated with 500, 1,000, 5,000, 10,000, and 20,000 eggs + second-stage juveniles (J2) of M. enterolobii per plant. Root and shoot fresh weights, shoot dry weight, root length, plant height, and stem base diameter were evaluated at 70 and 135 days after inoculation (DAI). Total number of M. enterolobii eggs + J2 in the root system and nematode reproduction factor nematode were assessed. Nematode multiplication in roots was not proportional to increases in initial inoculum density; thus, the best plant responses to nematode multiplication in the evaluated cultivar were found for the lowest tested densities. The reproduction factor decreased as the inoculum density was increased, at both evaluations (70 and 135 DAI). Syn.

ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

RESUMO A goiabeira é uma cultura de grande importância para o mundo, no entanto, um grave problema fitossanitário, causado pelo parasitismo de Meloidogyne enterolobii, tem limitado a produtividade da cultura no Brasil e em diversos países. A incidência do nematoide resulta em acentuada queda de produtividade e, na maioria das vezes, as plantas morrem em médio prazo. Visando a contribuir com ferramentas de controle, avaliou-se a reação de 37 acessos de Psidium guajava em casa de vegetação quanto à resistência a M. enterolobii. As mudas de cada acesso foram produzidas a partir de sementes e, no estádio de três a seis pares de folhas, foram submetidas à inoculação com 4.000 ovos de M. enterolobii, em dois experimentos. Cento e trinta e cinco dias após a inoculação, coletou-se o sistema radicular de cada uma das plantas para a extração de ovos. As contagens de ovos foram feitas em três alíquotas de 1 mL/planta e foram submetidas à análise de variância que indicou diferenças significativas entre acessos e entre plantas de mesmo acesso. A classificação dos acessos quanto à resistência foi feita pelo fator de reprodução (FR=Pf/Pi, Pi= 4.000). Pelo estudo do germoplasma de P. guajava, observou-se grande variabilidade quanto à reação a M. enterolobii, sendo que, no Experimento I, plantas resistentes foram encontradas nos acessos A08, A15, A26, A13 e A30A e, no Experimento II, nos acessos A31, A11, A16, A30A, GF3 e A08, com a detecção de plantas resistentes nos acessos A08 e A30A nos dois experimentos. mundo entanto fitossanitário enterolobii países vezes prazo controle avaliouse avaliou se 3 M folhas 4000 4 000 4.00 experimentos coletouse coletou mLplanta mL planta FR=Pf/Pi, FRPfPi FR Pf Pi (FR=Pf/Pi 4.000. . 4.000) P observouse observou I A15 A26 A1 AA II A31 A11 A16 GF A0 400 00 4.0 FR=Pf/Pi A2 A3 40 0 4.
ABSTRACT Guava is a highly important fruit crop worldwide; however, a severe phytosanitary problem caused by the parasitism of Meloidogyne enterolobii has been limiting guava yields in Brazil and in several countries. The incidence of the nematode M. enterolobii results in significant decreases in yield, often resulting in plant death in the medium term. Considering a contribution to control tools, the objective of this study was to assess the resistance of 37 accessions of Psidium guajava grown in a greenhouse to M. enterolobii. Seedlings from seeds of each accession were inoculated with 4,000 eggs of M. enterolobii when they were at the three- to six-leaf stage, in two experiments. The root system of each plant was collected at 135 days after inoculation for extracting nematode eggs. The eggs were counted in three aliquots of 1 mL plant-1, and the obtained data were subjected to analysis of variance, which showed significant differences among accessions and among plants of the same accession. Accessions were classified regarding resistance based on the reproduction factor (RF = Pf / Pi = 4,000). The P. guajava germplasm studied showed a significant variability in responses to M. enterolobii; resistant plants were identified for accessions A08, A15, A26, A13, and A30A in Experiment I and for accessions A31, A11, A16, A30A, GF3, and A08 in Experiment II; the accessions A08 and A30A stood out by presenting resistant plants in both experiments. worldwide however countries M yield term tools 3 4000 4 000 4,00 sixleaf six leaf stage experiments 13 plant1, plant1 1, plant-1 variance RF 4,000. . 4,000) P A A15 A26 A13 AA A31 A11 A16 GF3 GF A0 II 400 00 4,0 plant- A1 A2 A3 40 0 4,

Resumo O uso de inseticidas botânicos tem aumentado nos últimos anos devido à demanda por produtos eficazes, especialmente contra insetos resistentes aos inseticidas convencionais. Entre eles está o Aedes aegypti, um mosquito bem adaptado a ambientes urbanos que se alimenta oportunisticamente de humanos e animais, contribuindo para dispersão de vírus. Avaliamos o potencial de óleos essenciais (OEs) extraídos de Eucalyptus citriodora, Eucalyptus staigeriana, Eucalyptus caryophyllus e Mentha arvensis em relação à sua atividade larvicida contra Ae. aegypti. Os compostos dos OEs foram determinados usando cromatografia gasosa acoplada à espectrometria de massa (GC-MS). Os bioensaios foram realizados em larvas de terceiro instar de Ae. aegypti para avaliar os efeitos larvicidas das diluições de OE em dimetil sulfóxido (DMSO) em diferentes concentrações. As taxas de mortalidade foram observadas ao longo de 72 horas para determinar a eficácia dos tratamentos. O componente citronelal (86,64) predominou em E. citriodora, limoneno em E. staigeriana (41,68), eugenol em E. caryophyllus (87,76) e mentol em M. arvensis (50,73%). Os OEs exibiram atividade larvicida a partir de 10 ppm, com grande eficácia a 85 ppm, onde os de E. staigeriana e M. arvensis causaram mortalidade máxima de larvas de Ae. aegypti. Os resultados revelaram padrões de eficácia distintos entre os OEs, com E. staigeriana exibindo maior toxicidade dentro de 24 horas, alcançando valores de CL50 e CL95 de 47,04 ppm e 97,35 ppm, respectivamente. Efeitos larvicidas dentro de 1 hora foram observados para E. citriodora e E. caryophyllus. Este estudo destaca a eficácia larvicida contra Ae. aegypti, especialmente E. staigeriana, que teve o menor valor de CL50.

Abstract The use of botanical insecticides has increased in recent years due to the demand for effective products, particularly against insects resistant to conventional insecticides. Among these is Aedes aegypti, a well-adapted mosquito to urban environments that opportunistically feeds on humans and animals, contributing to the spread of virus. We evaluated the potential of essential oils (EOs) extracted from Eucalyptus citriodora, Eucalyptus staigeriana, Eucalyptus caryophyllus, and Mentha arvensis in terms of their larvicidal activity against Ae. aegypti. EOs’ compounds were determined using gas chromatography-mass spectrometry (GC-MS). Bioassays were performed on third instar larvae of Ae. aegypti to evaluate the larvicidal effects of EO dilutions in dimethyl sulfoxide (DMSO) at different concentrations. Mortality rates were observed over a 72-hour period to determine the efficacy of the treatments. Citronellal (86.64) predominated in E. citriodora, limonene in E. staigeriana (41.68), eugenol in E. caryophyllus (87.76), and menthol in M. arvensis (51.53%). EOs exhibited larvicidal activity from 10 ppm, with notable efficacy at 85 ppm, in which those from E. staigeriana and M. arvensis caused maximum mortality to Ae. aegypti larvae. Results revealed distinct efficacy patterns among EOs, with E. staigeriana displaying high toxicity within 24 h, achieving LC50 and LC95 values of 47.04 ppm and 97.35 ppm, respectively. Larvicidal effects within 1 h were observed for E. citriodora and E. caryophyllus. This study underscores larvicidal efficacy against Ae. aegypti, notably E. staigeriana, which had the lowest LC50 value. The findings indicate that the tested samples have potential for use as bioinsecticides. products welladapted well adapted animals virus (EOs Ae chromatographymass chromatography mass GCMS.

Resumo A incorporação de materiais alternativos em substituição parcial ao clínquer é estudada afim de diminuir a emissão de CO2 que ocorre na produção do cimento Portland. Analisou-se a influência do uso da cinza de algaroba como fíler alternativo em pastas de cimento LC3. O teor de álcali do sistema foi ajustado lavando a cinza e, assim, reduzindo o teor de potássio. O fíler foi substituído em 0, 25%, 50%, 75% e 100% de cinza lavada e o mesmo para cinza não lavada. A subsulfatação foi corrigida adicionando-se uma porcentagem de gesso extra. O desempenho da pasta foi avaliado pela reologia e resistência à compressão, sustentada pela cinética de hidratação e desenvolvimento microestrutural. A cinza de algaroba é um potencial fíler alternativo para aplicação em LC3.

Abstract The incorporation of alternative materials in partial replacement of clinker is studied to reduce the CO2 emissions that occur in the production of Portland cement. The influence of using mesquite ash as an alternative filler in LC3 cement pastes was analyzed. The alkali content of the system was adjusted by washing the ash, thus reducing the potassium content. The filler was replaced at 0, 25%, 50%, 75%, and 100% washed ash, and the same for unwashed ash. Subsulfation was corrected by adding an extra gypsum percentage. Paste performance was assessed by rheology and compressive strength, supported by hydration kinetics and microstructural development. Mesquite ash is a potential alternative filler for application in LC3. Washed ash makes the system purer, contributing to hydration and mechanical performance, however, natural ash also brings promising results.

Methods: A cross-sectional study included 343 adolescents with immunocompromising diseases and 108 healthy adolescents. Online questionnaires were answered including socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and validated surveys: Strengths and Difficulties Questionnaire (SDQ), Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0). Results: The frequencies of abnormal emotional SDQ scores from adolescents with chronic diseases were similar to those of healthy subjects (110/343 [32%] vs. 38/108 [35%], p = 0.548), as well as abnormal hyperactivity/inattention SDQ scores (79/343 [23%] vs. 29/108 [27%], p = 0.417). Logistic regression analysis of independent variables associated with abnormal emotional scores from adolescents with chronic diseases showed: female sex (Odds Ratio [OR = 3.76]; 95% Confidence Interval (95% CI) 2.00–7.05; p < 0.001), poor sleep quality (OR = 2.05; 95% CI 1.08–3.88; p = 0.028) and intrafamilial violence during pandemic (OR = 2.17; 95% CI 1.12–4.19; p = 0.021) as independently associated with abnormal emotional scores, whereas total PedsQL score was inversely associated with abnormal emotional scores (OR = 0.95; 95% CI 0.93–0.96; p < 0.0001). Logistic regression analysis associated with abnormal HI scores from patients evidenced that total PedsQL score (OR = 0.97; 95% CI 0.95–0.99; p = 0.010], changes in medical appointments during the pandemic (OR = 0.39; 95% CI 0.19–0.79; p = 0.021), and reliable COVID-19 information (OR = 0.35; 95% CI 0.16–0.77; p = 0.026) remained inversely associated with abnormal HI scores. Conclusion: The present study showed emotional and HI disturbances in adolescents with chronic immunosuppressive diseases during the COVID-19 pandemic. It reinforces the need to promptly implement a longitudinal program to protect the mental health of adolescents with and without chronic illnesses during future pandemics.

ABSTRACT Semi-mechanized and mechanized harvesting use machines that promote the transference of vibrational energy and impact to achieve the detachment of coffee fruits. The aim of this study was to evaluate the vibration transmissibility in coffee fruit-peduncle systems, using high-speed cameras, submitted to high frequency harmonic excitation in different combinations between frequency and amplitude of vibration, identifying working ranges suitable to perform selective harvesting. Vibration transmissibility was determined for the coffee fruit-peduncle systems, for the maturation stages unripe and ripe that were subjected to a sinusoidal harmonic displacement, in which the input parameters were frequency (35, 45 and 55 Hz) and peak-to-peak amplitude (3.5, 5.0 and 6.5 mm). An experiment was used to study the effect of frequency and amplitude on vibration transmissibility in a completely randomized design in a factorial scheme 3 x 3 x 2, with three replications. The frequency of 35 Hz, associated with the amplitudes 3.5-6.5 mm, was the one that most influenced the results of vibration transmissibility. For the frequency of 55 Hz and amplitude of 6.5 mm, in the ripe maturation stage, the vibration transmissibility was higher than 1.0, which could be a suitable combination for selective coffee harvesting.

AISI 6160 steel is used to manufacture cutting blades and springs due to its high tensile strength and good ductility. However, it has low mechanical strength and low wear resistance. In this work, a duplex treatment consisting of CCPD followed by PN was performed to improve the surface properties of the steel. In addition, XRD, optical microscopy, microhardness, and sphere-disk tribological analysis were used to verify the surface changes of the samples. The results showed a significant improvement in surface hardness and better wear resistance of AISI 6160 Steel submitted to Duplex treatment. The sample submitted to the CCPD treatment for 4 hours and, after nitriding at 500 °C for 2 hours, presented higher surface hardness and wear resistance than the sample only subjected to plasma deposition, characterizing the efficiency of the use of the duplex treatment adopted in the present work. 616 ductility However work addition XRD microscopy microhardness spheredisk sphere disk samples 50 C deposition 61 5 6

ABSTRACT In this work we propose an algorithm based on the Constrained Constructive Optimization (CCO) method that generates a geometric model of the vascular system structure with n trees, considering fisiological conditions of flow, pressure, and taking into account the minimum intravascular volume while constructing the model. We use this algorithm to generate a geometric model of some vascular system on a convex two-dimensional perfusion domain. The results show that the model replicates morphometric features found in real vascular trees. CCO (CCO trees flow pressure twodimensional two dimensional domain
