Co-creation and brand identity within the context of a football club: do the fans co-influence the brand identity of Sport Lisboa Benfica?

The concept of co-creation has been extensively discussed recently both in literature and in practice. Nevertheless, researchers struggle to agree on a single universal definition. For the purpose of this dissertation we define co-creation as “joint collaborative activities by parties involved in direct interactions, aiming to contribute to the value that emerges for one or both parties” (Grönroos, 2008). Additionally, not all brands fulfill the necessary conditions to ensure co-creation. Football club brands, after thorough analysis, are assumed to be a case worthy to study in this context (Healy & McDonagh, 2013; Pongsakornrungsilp & Schroeder, 2011). With the goal of extending knowledge on the topic, we developed a longitudinal single case study, based on qualitative in-depth interviews, studying co-creation in the context of a Portuguese football club brand – Sport Lisboa Benfica. The research brings important insights to the theory of brand identity construction and development, since it demonstrates that the interactions between consumers (i.e., fans) and the brand managers impact the brand identity. We conclude that consumers co-create with football club brands and co-influence their brand identity, together with the managers. Other implications are also discussed in this thesis

Diet of the White Stork (Ciconia ciconia) in a heterogeneous Mediterranean landscape: the importance of the invasive Red Swamp Crayfish (Procambarus clarkii)

Limited quantitative data are available on food habits of the White Stork (Ciconia ciconia) in Mediterranean environments, particularly in ricefields where a relatively new food resource, the invasive Red Swamp Crayfish (Procambarus clarkii), is abundant. We studied the diet of the White Stork in a heterogeneous landscape (Central Portugal) in order to compare the importance of the Red Swamp Crayfish as a food resource in a dominant agricultural/ricefield area in rela - tion to a predominant woodland/agricultural area. White Storks´ diet was analysed spatially (two sites) and seasonally (winter, spring, summer) using pellets (n = 122) collected between December 2012 and July 2013. Overall, from 1570 prey items identified, crayfish was the second most frequent and abundant prey in the diet (frequency of occurrence, FO = 79.5%; numerical fre- quency, NF = 22.9%, respectively), only surpassed by coleopterans (FO = 94.3%; NF = 57.7%). However, in terms of consumed biomass (global PB) crayfish dominated the diet (PB = 44.0%),representing 1.8 times the consumed biomass of coleopterans (PB = 24.2%). Consumption of crayfish was higher in the site with highest abundance of ricefields (NF: 32.0% vs. 17.7%; PB: 51.3% vs. 38.4%). Although no significant seasonal variations were detected in terms of the number of crayfish consumed by storks, consumed crayfish biomass was significantly higher in summer in relation to other seasons. Our findings suggest that in Mediterranean heterogeneous areas the White Stork feeds upon a wide range of prey taxa though, when available, coleopterans along with Red Swamp Crayfish dominate the diet

Evaluation of the rubber seed shell (hevea brasiliensis) as an adsorbent: kinetic study/Avaliação da casca da semente de borracha (hevea brasiliensis) como adsorvente: estudo cinético

This study consisted in a technical evaluation of the adsorption process as a treatment for effluents contaminated by dyes. Due to that, a methyl orange solution was used in order to simulate a textile effluent, and the rubber seed shell was used as an adsorbent. It was evaluated an untreated seed shell (CS), the calcinated seed shell (CCS) and the calcinated shell that was also submitted to a chemical treatment using a solution of HNO3 15% (CCS-T). The experiments were performed in a batch mode to evaluate the individual efficiency of each treatment. The adsorbent’s mass and the initial concentration of the solutions used were remained constant at 0.15 g and 100 mg/L, respectively. The absorbance analysis was done for all the samples obtained during 6 h of operational time. The results indicated that the CCS-T provided the best efficiency in the removal of methyl orange dye, reducing its concentration to 55.98 mg/L, whereas the use of the CCS achieved a value of only 75.53 mg/L. It was not observed adsorption using CS. The maximum adsorption capacity of methyl orange was 7.59 mg/g, through the CCS-T adsorbent. Two kinetic models were used to model the experimental data obtained with the CCS-T adsorbent, with the pseudo-first order model providing the best correlation with the experimental data

The effect of Crude Glycerin of Low Purity Replacing Corn on Goats’ Diets in Feedlot in Semiarid Areas

The objective of this study was to evaluate the effects of crude glycerin (CG) on the diet of goats in feedlot, in terms of intake and nutrient digestibility, performance, feeding behavior, and metabolic profile. Forty castrated male goats with breed undefined and an average initial body weight of 19.7±2.3 kg were used. The experimental diets consisted of inclusion of CG at 0, 6, 12 and 18 % (based on DM). The DM (g/day), DM (g/kg), organic matter, crude protein, neutral detergent fiber, non-fiber carbohydrate, total digestible nutrients, and water intakes were decreased linearly with increasing CG levels, whereas ether extract intake increased linearly. The daily time spent (%) and average duration of events (h/d) for rumination presented a linear increase, although reduced for idling, as well as feeding and rumination efficiencies. The inclusion of CG did not affect the final body weight, total weight gain, and average daily gain. Serum cholesterol concentration presented a linear increasing effect. However, beta-hydroxybutyrate level was reduced. Crude glycerin containing 63.06% glycerol may partially replace corn and be included at a concentration of up to 18% of dry matter in the diet of finished goats in feedlot when moderate weight gains are desired, especially beneficial in semiarid regions

Enantioselective Synthesis, DFT Calculations, and Preliminary Antineoplastic Activity of Dibenzo 1-Azaspiro[4.5]decanes on Drug-Resistant Leukemias

The addition of 2-bromobenzylmagnesium bromide to chiral N-tert-butanesulfinyl imines derived from tetralone-type ketones proceeds with high levels of diastereocontrol. The resulting sulfinamide derivatives were transformed into dibenzoazaspiro compounds after a palladium-catalyzed intramolecular N-arylation. DFT calculations have been performed to rationalize the stereochemical course of the reaction. Similar results have been obtained considering either diethyl ether or toluene as a solvent, in both cases in an excellent agreement with experimental findings. NCI topological calculations have also been used to evidence crucial noncovalent interactions. In addition, the azaspiro compounds reduced the viability of chronic myeloid leukemia cells in the micromolar range. Notably, both the halogen-substituted (R)- and (S)-8g and -8h as well as (R)-8j were at least two times more effective on a multidrug-resistant derivative than on the parental cell line, exerting a collateral sensitivity effect.We acknowledge the continued financial support from the Spanish Ministerio de Economía y Competitividad (MINECO; project CTQ2014-53695-P, CTQ2014-51912-REDC, CTQ2016-81797-REDC, CTQ2016-76155-R, CTQ2017-85093-P), FEDER, the Generalitat Valenciana (PROMETEOII/2014/017), and the University of Alicante.

Morphometric analysis of the esophagus-gastric transition in horse submitted to different feeding management and physical activities

O objetivo deste trabalho foi identificar se diferentes tipos de manejo físico e alimentar determinaram mudanças adaptativas na morfometria da região de transição esôfago-gástrica (TEG) em eqüinos. Foram utilizados 15 conjuntos de animais adultos com raça, sexo e idade não identificados, divididos em três grupos de acordo com a dieta e a atividade física: grupo I - composto por cinco conjuntos da TEG de eqüinos em treinamento intensivo e alimentados principalmente à base de concentrado; grupo II - com cinco conjuntos da TEG de eqüinos que não desempenhavam atividade física intensa e eram alimentados principalmente à base de concentrado, e o grupo III - composto por cinco conjuntos da TEG de eqüinos mantidos a pasto e que não desempenhavam atividade física intensa. A região de transição esôfago-gástrica teve a estrutura do seu epitélio avaliada morfometricamente, onde foram feitas mensurações para identificar a espessura do epitélio estratificado pavimentoso queratinizado. A espessura do grupo I teve como média 122,3µm, do grupo II foi de 173,4µm e do grupo III foi de 281,7µm. Os resultados encontrados para a espessura do epitélio estratificado pavimentoso queratinizado dos eqüinos mostraram a existência de diferenças estatisticamente significativas dos eqüinos do grupo I, quando comparados aos eqüinos do grupo III.The objective of this research was to identify if different kind of physical and alimentary management determine adaptative changes in morphometry of the esophagus-gastric transition epithelium. 15 sets comprehending the esophagus-gastric transition region (TEG) was used in adult horses considering undefined breed, gender and age divided in three groups according to diet and physical activity: group I – Five sets (TEG) of horses in intensive training fed with commercial ration; group II – Five sets (TEG) of horses which did not develop any intensive physical activity and fed by commercial ration; group III – Five sets (TEG) of horses kept in the grass without any extra feeding which did not develop any intensive physical activity. The esophagus-gastric transition region had its epithelium structure evaluated morphometrically where measurements were done to identify the thickness of the stratified squamous keratinized epithelium. The thickness of the grup I had as average 122.3µm, grup II 173.4µm of grup III 281.7µm. Results of stratified squamous keratinized epithelium thickness have shown the existence of statistically significant differences of group I when compared to group III

Macroscopic analysis of the esophagus-gastric transition area in horses submitted to different feeding management and physical activities

Estudou-se a região de transição esôfago-gástrica dos eqüinos, pois diversos fatores distintos podem causar lesões nessa região ou, ainda, na região aglandular do estômago destes animais. O objetivo deste trabalho foi verificar se diferentes tipos de manejo físico e alimentar determinam alterações na estrutura macroscópica da região de transição esôfago-gástrica de eqüinos. Foram utilizados 15 conjuntos, compreendendo a região de transição esôfago-gástrica de eqüinos adultos, com raça, sexo e idade não identificados, divididos em três grupos de acordo com a dieta e atividade física desenvolvida: Grupo I, cinco conjuntos de eqüinos em treinamento intensivo e alimentados à base de concentrado, principalmente; Grupo II, cinco conjuntos de eqüinos que não desempenhavam atividade física intensa e eram alimentados à base de concentrado, principalmente; e o Grupo III, com cinco conjuntos de eqüinos mantidos a pasto, que não desempenhavam atividade física intensa. Os resultados mostraram que a coloração da mucosa variou entre os grupos, bem como a espessura da parede da região de transição. Verificou-se a presença de úlceras gástricas em todos os grupos estudados; no entanto, a maior incidência foi identificada na transição esôfago-gástrica dos eqüinos do Grupo II. Concluiu-se que não foi possível efetuar nenhuma correlação entre a dieta e atividade física com as alterações macroscópicas, ou seja, a presença de úlceras na parede da região de transição esôfago-gástrica dos eqüinos avaliados. _________________________________________________________________________________ ABSTRACTThe region of esophagus-gastric transition of equines was studied since distinct factors can cause injuries in this region as well as in the glandular region of the stomach of these animals. The objective of this work was to identify whether different types of physical and alimentary handling determine alterations in the macroscopic structure of the region of esophagus-gastric transition of the equines. We used 15 sets consisting of the regions of esophagus-gastric transition of adult equines whose race, sex and age were unidentified, divided into three groups in accordance with the diet and developed physical activity: Group I, five sets of equines in intensive training and fed mainly on the basis of concentrate; Group II, five sets of equines that did not engage in intense physical activity and were fed mainly on the basis of concentrate; and Group III with five sets of equines kept on pasture that did not engage in intense physical activity. The results showed that the staining of the mucosa, as well as the wall thickness of the region of transition, varied among groups. Gastric ulcers were found in all the groups studied, but most of them were identified in the transitions of the equines of Group II. The study concludes that no correlation existed between the macroscopic diet/physical activity and the presence of ulcers in the wall of esophagus-gastric transition of the equines

Characterization Of Chemically Induced Ovarian Carcinomas In An Ethanol-preferring Rat Model: Influence Of Long-term Melatonin Treatment.

Ovarian cancer is the fourth most common cause of cancer deaths among women, and chronic alcoholism may exert co-carcinogenic effects. Because melatonin (mel) has oncostatic properties, we aimed to investigate and characterize the chemical induction of ovarian tumors in a model of ethanol-preferring rats and to verify the influence of mel treatment on the overall features of these tumors. After rats were selected to receive ethanol (EtOH), they were surgically injected with 100 µg of 7,12-dimethyl-benz[a]anthracene (DMBA) plus sesame oil directly under the left ovarian bursa. At 260 days old, half of the animals received i.p. injections of 200 µg mel/100 g b.w. for 60 days. Four experimental groups were established: Group C, rats bearing ovarian carcinomas (OC); Group C+EtOH, rats voluntarily consuming 10% (v/v) EtOH and bearing OC; Group C+M, rats bearing OC and receiving mel; and Group C+EtOH+M, rats with OC consuming EtOH and receiving mel. Estrous cycle and nutritional parameters were evaluated, and anatomopathological analyses of the ovarian tumors were conducted. The incidence of ovarian tumors was higher in EtOH drinking animals 120 days post-DMBA administration, and mel efficiently reduced the prevalence of some aggressive tumors. Although mel promoted high EtOH consumption, it was effective in synchronizing the estrous cycle and reducing ovarian tumor mass by 20%. While rats in the C group displayed cysts containing serous fluid, C+EtOH rats showed solid tumor masses. After mel treatment, the ovaries of these rats presented as soft and mobile tissues. EtOH consumption increased the incidence of serous papillary carcinomas and sarcomas but not clear cell carcinomas. In contrast, mel reduced the incidence of sarcomas, endometrioid carcinomas and cystic teratomas. Combination of DMBA with EtOH intake potentiated the incidence of OC with malignant histologic subtypes. We concluded that mel reduces ovarian masses and the incidence of adenocarcinomas in ethanol-deprived rats.8e8167

CFD modeling of combustion of sugarcane bagasse in an industrial boiler

In this study, a CFD model is developed to evaluate the performance of an industrial boiler furnace running on sugarcane bagasse. The model was developed in the commercial software ANSYS FLUENT and includes user-defined functions programmed in C language defining devolatilization phenomenon as well as combustion on the grate. The simulation results suggests that devolatilization is the dominant phenomenon through the largest portion of the particle trajectory, and hence an important factor in predicting the thermal fields. On the other hand, the char is burned on the grate or entrained through the furnace outlet. The general efficiency indicators obtained from particle combustion description could then allow us to compare different design and operational alternative
