The field of closed-loop supply chain management (CLSCM) seeks to replace the linear flow materials and energy with a cyclical model in which outputs production system become inputs same system, thus closing cycle within chain. Current literature on CLSCM reports wide variety practices, combining these practices environmental performance measures is an ongoing challenge, mainly because results from are often diffuse linking them not straightforward task. This paper addresses this problem by...

binder deposition, inkjet printing, material jetting, powder bed fusion, photopolymerization, pen-based 3D printing and molding, have been reported in the literature [8,9].Fused

This experimental study investigates the bioactive potential of filaments produced via hot melt extrusion (HME) and intended for fused deposition modeling (FDM) 3D printing purposes. The oleo-gum-resins from benzoin, myrrha, olibanum in pure state also charged with 10% metal oxide nanoparticles, TiO2, P25, Cu2O, MoO3, were characterized by ultraviolet-visible (UV-Vis) Fourier transform infrared (FTIR) spectroscopy, energy-dispersive X-ray microanalysis (EDXMA), scanning electron microscopy...

This work aimed to identify the legacy left by 2014 World Cup in Brazil regarding tourism development and urban mobility. A qualitative research was performed using descriptive statistics assist discussion. Data were gathered from Brazilian Government Fédération Internationale de Football Association – FIFA. Results pointed out that foreseen investments not fulfilled. Failure carry all projects actions judged necessary justified mega-event confirmed hypothesis expenditures underestimated...

Conductive and magnetic filaments are revolutionizing three-dimensional printing (3DP) to a new level. This review study presents the current state of art on subject, summarizing recent high impact studies about main advances regarding application 3DP based carbon nanostructures such as graphene, fibers, nanotubes, conductive black embedded in polymer matrix, by reviewing its characteristics showing producers also products available market. The availability inexpensive, reliable,...

Restaurants are one of the main sources wealth in tourism sector and have significant potential fight against poverty reduction lack development local communities. However, relation to emission greenhouse gases generation waste, they seen as two less sustainable sectors world. This study has objective providing a method determine level sustainability restaurants by means modeling OKR fuzzy logic. For this, 100 key results from environmental, social, economic dimensions were selected, using...

Looking for alternatives to promote the diversification of Brazilian energy grid through utilization renewable fuels, this forecasting study evaluates potential generate thermal from lignins extracted several crops in period 2015–2021. The estimates were carried out taking into account two biomass particle size distributions (ranged between 105–500 µm and 1000–2000 µm) extraction methods (Klason Willstatter) assess lignin yields obtained five well‐known crops. Results revealed that sugarcane...

Purpose The coronavirus disease (COVID-19) pandemic generated a worldwide financial crisis by impacting several links of the supply chain, however companies can take advantage quantitatively measuring disruptive impacts. Design/methodology/approach This study sought to develop failure mode and effect analysis chain resilience (FMEA-SCR), hybrid tool developed using potential (FMEA) applied (SCR) taking into account capability factors business processes. Findings In order validate, proposed...

This paper main objective is to determinate the hydrolysis efficiency by using four different diluted acids treatment: (H 2 SO 4 ) sulfuric, (HNO 3 nitric, phosphoric PO and acetic (CH COOH), in attempt improve fibers bioethanol production levels. In this study twelve Brazilian woods were investigated, including native exotic species, hardwoods softwoods. Processes use wood waste recovery established produce ethanol cellulosic simultaneously carried out. For fermentation essay, a wild line...

This study quantifies the extraction performance and some properties of lignin obtained from six crops with potential for generating thermal energy in Brazil. A full factorial design (22) four replicates including two methods particles size distributions was adopted assessing fraction lignin, as well its Higher Heating Value (HHV) composition given by proximate ultimate analysis. It verified that all cases HHV is greater than respective raw material, suggesting these lignins could be also...

In this study we demonstrated the inactivation of E. coli, C. difficile, meshophilic bacteria and Salmonella spp. through Pulsed Electric Field (PEF) technology. First, a simulation using Finite Element Method Magnetics Mathematical Modeling was used to obtain electric field values be in electro-pasteurization tunnel. Then, practical tests were carried out by an industrial scale apparatus set with following parameters: pulse 20 s – 40 s, 40, 80 450 kV, radio frequency 350 kHz treadmill speed...

Purpose This paper aims to identify the determining factors for financial performance (FP) of social enterprises in an emerging country, this case Brazil. Design/methodology/approach identifies determinants FP Brazil using resource-based view as a theoretical lenses and quantitative method ( n = 601) logistic regression, analyzing importance nine variables related SEs. Findings The findings refer practical contributions (which show how SEs should focus allocate their resources maximize FP)...

Infection caused by the human papillomavirus (HPV) is common among sexually active population worldwide. With 200 known genotypes, 15 of them are considered high-risk oncogenic, with types 16 and 18 being most associated anogenital head/neck cancers. The cell cycle, consisting G1, S, G2, M phases, regulated tumor suppressor genes such as Rb p53, whose dysregulation can result in continuous replication damaged cells. High-risk HPVs related to neoplasias, immune response typically eliminates...

Wood wastes are potential material for second generation ethanol production within the concept of residual forest bio-refinery. Current paper reports on employing an HPLC method monitoring chemical content dispersed in hydrolysate liquor after fermented. The proton-exchange technique was analytical employed. Twelve types wood chips were used as biomass, including Hymenolobium petraeum, Tabebuia cassinoides, Myroxylon peruiferum, Nectandra lanceolata, Ocotea catharinensis, Cedrelinga...

This study is aimed at recognizing how knowledge captured, created, stored and used in two incubated companies. The survey was conducted the “Intecponta Incubator”, located city of Ponta Grossa - PR, South Brazil. Knowledge Management Diagnostic (KMD) proposed by Bukowitz Williams (2002) applied. efforts made were regard to understand if method could be identifying generation consequently increase performances. data collection occurred through a questionnaire answered managers. KMD divided...

Transportation is vital to life in society; it enables economic, social, and environmental development through connections between areas, cities, countries, facilitating interactions integrations. However, transportation one of the sectors that most impacts sustainability, causing, among other things, emissions gases, noise, accidents.
