Purpose: The purpose of this study was to investigate the impact of radiotherapy on mandibular bone tissue in head and neck cancer patients through an analysis of pixel intensity and fractal dimension values on digital panoramic radiographs. Materials and Methods: Thirty patients with radiographic records from before and after 3-dimensional (3D) conformational radiotherapy were selected. A single examiner carried out digital analyses of pixel intensity values and fractal dimensions, with the areas of interest unilaterally located in the right angle medullary region of the mandible below the mandibular canal and posterior to the molar region. Results: Statistically significant decreases were observed in the mean pixel intensity (P=0.0368) and fractal dimension (P=0.0495) values after radiotherapy. Conclusion: The results suggest that 3D conformational radiotherapy for head and neck cancer negatively affected the trabecular microarchitecture and mandibular bone mass.

Water is an important resource necessary for the survival of the human race and the ecosystem which we are apart of. Today many countries globally are facing the challenge of water scarcity resulting in a constant struggle for the economic and social development of these countries. Integrated Water Resource Management(IWRM) through fostering shared value is the solution to these water issues countries are currently facing particularly since it is cost effective and can be achieved in a sustainable manner. Therefore the goal of this paper is to present a viable solution to solve the challenges of managing water resource for future use in developing countries through creating shared value. The design of this paper is to provide a conceptual overview of IWRM through the use of co-creation with stakeholders. In addition a qualitative study employing a grounded theory approach to derive a conceptual model for a co-creative approach to IWRM in developing countries through fostering shared value will be employed. The findings for this research suggested that co-creation is the new solution to IWRM within developing countries. Particularly, since it harness and integrates knowledge, and viable solutions from various stakeholders within a country and worldwide to solve critical problems, while generating shared value for all stakeholders. This paper contributes to the practical, social and academic literature that currently exists regarding IWRM. This is an original paper that presents a viable strategy, through the use of co-creation, for the IWRM in developing countries.

Palma, M.N.N.,Rocha, G.C.,Valadares Filho, S.C.,Detmann, E. Asian Australasian Association of Animal Productio 2015 Animal Bioscience Vol.28 No.11

Rigorously standardized laboratory protocols are essential for meaningful comparison of data from multiple sites. Considering that interactions of minerals with organic matrices may vary depending on the material nature, there could be peculiar demands for each material with respect to digestion procedure. Acid digestion procedures were evaluated using different nitric to perchloric acid ratios and one- or two-step digestion to estimate the concentration of calcium, phosphorus, magnesium, and zinc in samples of carcass, bone, excreta, concentrate, forage, and feces. Six procedures were evaluated: ratio of nitric to perchloric acid at 2:1, 3:1, and 4:1 v/v in a one- or two-step digestion. There were no direct or interaction effects (p>0.01) of nitric to perchloric acid ratio or number of digestion steps on magnesium and zinc contents. Calcium and phosphorus contents presented a significant (p<0.01) interaction between sample type and nitric to perchloric acid ratio. Digestion solution of 2:1 v/v provided greater (p<0.01) recovery of calcium and phosphorus from bone samples than 3:1 and 4:1 v/v ratio. Different acid ratios did not affect (p>0.01) calcium or phosphorus contents in carcass, excreta, concentrate, forage, and feces. Number of digestion steps did not affect mineral content (p>0.01). Estimated concentration of calcium, phosphorus, magnesium, and zinc in carcass, excreta, concentrated, forage, and feces samples can be performed using digestion solution of nitric to perchloric acid 4:1 v/v in a one-step digestion. However, samples of bones demand a stronger digestion solution to analyze the mineral contents, which is represented by an increased proportion of perchloric acid, being recommended a digestion solution of nitric to perchloric acid 2:1 v/v in a one-step digestion.

Motivating Producers to Participate in Co-Creation of Value

Producers are faced daily with the challenging task of creating value, by being innovative, within their organizations to survive the competitive global market. This paper aims at identifying the factors that motivates producers to participate in co-creation through the use of the grounded theory approach. Limited research is available on what and how producers are motivated to participate in co-creation. Therefore, this paper provides an academic contribution to the existing literature available as well as a practical perspective by providing producers with reasons why co-creation of value with consumes is vital for their survival.

In vitro Fermentation, Digestion Kinetics and Methane Production of Oilseed Press Cakes from Biodiesel Production

Olivares-Palma, S.M.,Meale, S.J.,Pereira, L.G.R.,Machado, F.S.,Carneiro, H.,Lopes, F.C.F.,Mauricio, R.M.,Chaves, Alex V. Asian Australasian Association of Animal Productio 2013 Animal Bioscience Vol.26 No.8

Following the extraction of oil for biodiesel production, oilseed press cakes are high in fat. As the dietary supplementation of fat is currently considered the most promising strategy of consistently depressing methanogenesis, it follows that oilseed press cakes may have a similar potential for $CH_4$ abatement. As such, this study aimed to characterise the nutritive value of several oilseed press cakes, glycerine and soybean meal (SBM) and to examine their effects on in vitro ruminal fermentation, digestion kinetics and $CH_4$ production. Moringa press oil seeds exhibited the greatest in sacco effective degradability (ED) of DM and CP (p<0.05). In vitro gas production (ml/g digested DM) was not affected (p = 0.70) by supplement at 48 h of incubation. In vitro DMD was increased with the supplementation of glycerine and SBM at all levels of inclusion. Moringa oilseed press cakes produced the lowest $CH_4$ (mg/g digested DM) at 6 and 12 h of incubation (p<0.05). The findings suggest that moringa oilseed press cake at 400 g/kg DM has the greatest potential of the oilseed press cakes examined in this study, to reduce $CH_4$ production, without adversely affecting nutrient degradability.

Poster Session:PS 0557 ; Oncology : Massive Bleeding as the First Clinical Manifestation of Metastatic Prostate Cancer Due to Primary Fibrinolysis, Successfully Treated with Aminocaproic Acid

Disseminated intravascular coagulation (DIC) is the most frequent coagulation disorder associated with metastatic prostate adenocarcinoma. However, DIC as an initial presentation of prostate cancer with primary fi brinolysis is extremely rare. The appropriate treatment to control bleeding in these situations is challenging, controversial and based on isolated case reports in the literature. A 66-year-old male presented at the emergency department with acute severe spontaneous ecchymoses localized to the limbs, latero-cervical hematoma and hemothorax. Prostate specifi c antigen level was 385 μg/L, bone scintigraphy revealed multiple bone metastases and prostate biopsy confi rmed adenocarcinoma (Gleason 9; 4+5). Laboratory investigation showed a pattern of primary fi brinolysis rather than the more common intravascular coagulation mechanism. Epsilon aminocaproic acid in monotherapy was initiated with a clear and rapid control of bleeding manifestations. This rare case of massive bleeding due to hyperfi brinolysis as the fi rst manifestation of prostate cancer suggests that in selected cases where the acute bleeding dyscrasia is clearly associated to a dominant fi brinolysis mechanism it is possible to use an approach of monotherapy with antifi brinolytics.
