Abstract

Soil CO2 emission (FCO2) is a critical component of the global carbon cycle, but it is a source of great uncertainty due to the great spatial and temporal variability. Modeling of soil respiration can strongly contribute to reducing the uncertainties associated with the sources and sinks of carbon in the soil. In this study, we compared five machine learning (ML) models to predict the spatiotemporal variability of FCO2 in three reforested areas: eucalyptus (RE), pine (RP) and native species (RNS). The study also included a generalized scenario (GS) where all the data from RE, RP and RNS were included in one dataset. The ML models include generalized regression neural network (GRNN), radial basis function neural network (RBFNN), multilayer perceptron neural network (MLPNN), adaptive neuro-fuzzy inference system (ANFIS) and random forest (RF). Initially, we had 32 attributes and after pre-processing, including Pearson's correlation, canonical correlation analysis (CCA), and biophysical justification, only 21 variables remained. We used as input variables 19 soil properties and climate variables in reforested areas of eucalyptus, pine and native species. RF was the best model to predict soil respiration to RE [adjusted coefficient of determination (R2 adj): 0.70 and root mean square error (RMSE): 1.02 µmol m−2 s−1], RP (R2 adj: 0.48 and RMSE: 1.07 µmol m−2 s−1) and GS (R2 adj: 0.70 and RMSE: 1.05 µmol m−2 s−1). Our findings support that RF and GRNN are promising for predicting soil respiration of reforested areas which could help to identify and monitor potential sources and sinks of the main additional greenhouse gas over ecosystems.

Weekly, data of body weight and chemical components of body free of feathers and feathers were collected from 1,200 chicks of four laying strains (Hisex Brown, Hisex White, Hy Line Brown and Hy Line White W36) until 18 weeks of age. The variables were subjected to two adjustments fixing, or not, some parameters of Gompertz function. The allometric model parameters were calculated for the chemical components. The lipid and protein composition of the body free of feathers were the components with the biggest change in the last weeks. Moreover, the chemical composition of the feather showed small variation. The parameters of the Gompertz function assumed values according to the employed adjustment, especially for protein and fat of the body free of feathers carcass. The adjustment of the Gompertz function by fixing the two parameters allowed coherence and biological significance. The allometric coefficients indicate that as the protein weight increased, the proportion of fat increased and the proportion of water and ashes in the body decreased. The fit of the model allows setting the parameters with consistency and biological significance without losing accuracy in the estimates. Departamento de Zootecnia Departamento de Ciências Exatas

Abstract

Objetivou-se com esta pesquisa descrever o potencial de retenção de nitrogênio por duas técnicas: abate comparativo e balanço de nitrogênio. Também se objetivou comparar os modelos ajustados para cada técnica e estimar as exigências de mantença para frangas de postura. Os ensaios foram realizados no período de 14 a 28, 56 a 70 e 98 a 112 dias de idade, utilizando 168 frangas. Os ensaios tiveram sete tratamentos e oito repetições. Os tratamentos consistiram de níveis de proteína variando de 75 a 435gkg-1 de matéria seca. As variáveis coletadas pelo abate comparativo foram nitrogênio ingerido e depositado e, pela técnica do balanço de nitrogênio, ingestão e excreção de nitrogênio. O intercepto da relação exponencial entre nitrogênio excretado e ingerido foi considerado a exigência de mantença. Os modelos ajustados foram comparados pelo teste da razão de máxima verossimilhança. As técnicas comparadas descreveram de forma diferente a exigência de mantença de nitrogênio. Para o abate comparativo, a exigência de mantença foi estimada em 342, 372 e 543mg/kgPC0,67 e para o balanço de nitrogênio foi de 342, 225 e 284mg/kgPC0,67, para os período de 14 a 28, 56 a 70 e 98 a 112 dias de idade, respectivamente. The objectives of this study were to describe the potential for nitrogen retention by two techniques: comparative slaughter and nitrogen balance; compare the adjusted models for each technique and estimate the maintenance requirement for pullets. Assays were performed during 14 to 28, 56-70 and 98 to 112 days of age, using 168 pullets. The design was completely randomized with seven treatments and eight replications. Treatments consisted of protein levels ranging from 75 to 435gkg-1 of dry matter. The variables were collected by comparative slaughter and nitrogen ingested and deposited in nitrogen balance technique intake and nitrogen excretion. The intercept of the exponential relationship between ingested and excreted nitrogen was considered a requirement for maintenance. The adjusted models were compared by using the maximum likelihood ratio. The techniques described differently compared the requirement for maintenance of nitrogen. For comparative slaughter requiring maintenance was estimated at 342, 372 and 543mg/kgPC0,67 and for nitrogen balance was 342, 225 and 284mg/kgPC0,67 for the period of 14 to 28, 56-70 and 98 to 112 days of age, respectively.

Abstract

The objectives of this study were to describe the potential for nitrogen retention by two techniques: comparative slaughter and nitrogen balance; compare the adjusted models for each technique and estimate the maintenance requirement for pullets. Assays were performed during 14 to 28, 56-70 and 98 to 112 days of age, using 168 pullets. The design was completely randomized with seven treatments and eight replications. Treatments consisted of protein levels ranging from 75 to 435gkg-1 of dry matter. The variables were collected by comparative slaughter and nitrogen ingested and deposited in nitrogen balance technique intake and nitrogen excretion. The intercept of the exponential relationship between ingested and excreted nitrogen was considered a requirement for maintenance. The adjusted models were compared by using the maximum likelihood ratio. The techniques described differently compared the requirement for maintenance of nitrogen. For comparative slaughter requiring maintenance was estimated at 342, 372 and 543mg/kgPC0,67 and for nitrogen balance was 342, 225 and 284mg/kgPC0,67 for the period of 14 to 28, 56-70 and 98 to 112 days of age, respectively.

Devido ao grande número de empregados e à criação de leis específicas para o registro eletrônico de ponto, foram necessárias adequações nesse procedimento. Nesse contexto, o presente trabalho buscou identificar e analisar o processo de adequação às leis do ponto eletrônico realizado por uma empresa do setor sucroenergético. Para tanto, realizou-se uma breve caracterização das empresas do setor quanto às formas de registro de ponto e opções de legislação. A partir disso, foi realizado um estudo de caso em uma empresa que optou pela terceirização da solução com tecnologia biométrica. Utilizou-se a pesquisa documental e entrevista para obtenção dos dados primários. Por meio dos dados coletados, foi possível entender o processo, seus custos e alterações geradas na empresa. As horas extras e o absenteísmo justificado diminuíram, ao contrário do absenteísmo não justificado, que aumentou. Foram identificados e classificados todos os custos de transação incorridos no processo. O trabalho contribui gerencialmente fornecendo um material de apoio para estudo de viabilidade de um projeto semelhante, tendo relevância para as áreas de gestão de pessoas e tecnologia. Por meio da Teoria dos Custos de Transação, uma base teórica pouco utilizada para explicar o fenômeno da terceirização na área da Tecnologia da Informação, o trabalho contribuiu no preenchimento dessa lacuna. Por fim, ressalta-se a relevância de realizar, em um único trabalho, a análise do impacto do sistema de registro eletrônico de ponto biométrico nos componentes da folha de pagamento. The sugar-energy sector occupies a great impact position on the Brazilian economy due to the financial movement and job creation. Due to the large number of employees and the creation of specific laws for electronic time-card system, adjustments were necessary in this procedure. In this context, the present work sought to identify and analyze the process of adaptation to the electronic time-card laws performed by a company in the sugar-energy sector. Therefore, a brief characterization of the companies in the sector was carried out regarding the method of time-card and options for legislation. From this, a case study was carried out in a company that opted to outsource the solution with biometric technology. Documentary research and interviews were used to obtain primary data. Through the collected data, it was possible to understand how the process went, its costs and changes generated in the company. Overtime and justified absenteeism decreased, in contrast to unjustified absenteeism, which increased. All transaction costs incurred in the process were identified and classified. The work contributes managerially by providing support material for the feasibility study of a similar project, having relevance to the areas of people management and technology. Through the Theory of Transaction Costs, a theoretical base little used to explain the phenomenon of outsourcing in the area of Information Technology, the work contributed to fill this gap. Finally, the relevance of carrying out, in a single work, the analysis of the impact of the electronic biometric point registration system on the payroll components is emphasized.

Grande parte dos projetos de sistemas de captação de energia por vibração utiliza excitação periódica em ressonância com a frequência natural do sistema para que a amplitude de vibração seja máxima, resultando em uma quantidade de energia desejável para transdução. No entanto, na natureza o espectro de vibração é grande, o que dificulta o projeto físico de um sistema de captação de energia com esse propósito, acrescenta-se que a vibração do ambiente é de baixa frequência, o que dificulta ainda mais o projeto de um dispositivo de tamanho reduzido. Acrescenta-se, ainda, que a vibração do ambiente, em geral, não permanece em uma única faixa, variando constantemente. Esse tipo de vibração do meio ambiente pode ser modelado como uma excitação não-ideal. O objetivo principal dessa tese é modelar um sistema de captação de energia por vibração para sistemas lineares e não-lineares, sujeitos a excitação periódica e não-ideal e projetar controladores para melhorar a interação do sistema de captação com a fonte de excitação aumentando sua eficiência. Como principal resultado, observou-se que a vibração não-ideal oferece mais energia ao sistema de captação do que a excitação periódica e que os controladores projetados, em especial o LMI, conseguiu atingir um resultado expressivo no ganho de eficiência Harvesting systems harness the energy from the environment such as solar, thermal, electromagnetic and vibrational. Many projects of vibration energy harvesting systems use harmonic excitation in resonance with the system natural frequency to maximum vibration amplitude, resulting in a desirable amount of energy to transduction. However , the ambient vibration spectrum is large, which hampers the physical design of a system to capture energy for this purpose , it adds that the vibration environment is low frequency , which further complicates the design of a device of reduced size. In addition the ambient vibration in general does not remain in a single band and varying constantly. The ambient vibration can be modeled as a non-ideal excitation. The main objective of this thesis is to model a linear and non-linear vibration energy harvesting systems subject to periodic and non-ideal excitation and project controllers to improve the interaction of the system with excitation source increasing its efficiency. As a main result, it was observed that the non-ideal vibration provides more energy to the harvesting system than periodic excitation and that the controllers designed in particular LMI, achieved a significant result in efficiency gain

Abstract

Background: Japanese quail breeders are the basis for genetic improvement and multiplication for commercial layers, however, there have been no known studies on the optimal lysine level for these birds. Thus, study the egg output response to the lysine (Lys) supply using different e-functions and evaluate the that best fit, have allowed the partition the lysine requirements for maintenance, both weight and egg output maximum., Methods: The objectives of this study were to identify the responses to various Lys levels, identify the functions related to these responses and determine the ideal Lys intake amount for Japanese quail breeders. A completely randomized design of seven treatments with seven replicated was used. Treatments consisted of diet supplementation by Lys in concentrations of 16.8, 11.8, 8.4, 6.7, 5.0, 3.4, and 1.7 g/kg. Six exponential models were adjusted., Results: The level of Lys was found to affect bird responses ( P  < 0.001). The birds responded to the levels provided, allowing for the creation of a lysine response curve. A monomolecular function with four parameters was balanced against the statistics of adjustment and selection of models. It was possible to estimate the level of lysine required for maintenance as 133 ± 2 mg/kg BW 0.67 , and based an average of 41% efficiency, 22 mg Lys produced 1 g of egg output (EO). The daily intake calculated by the monomolecular factorial model was 284 mg Lys for a bird with 0.170 kg body weight and production of 10 g EO/day. The four-parameter monomolecular function proposed in this study is adequate for interpreting the animal response and calculating lysine intake for breeders., Competing Interests: Tadia Emanuele Stivanin is employed by Vicami Codornas., (©2023 Carvalho et al.)
