Methods of discard ewes carcass suspension and the quality of meat

The objective of this study was to evaluate the carcass suspension method concerning quality of sheep meat. Ten discard ewes were used, with approximately 62 kg of body weight. After slaughtering, flaying, evisceration and removal of head and paws, carcasses were longitudinally divided into two parts. Alternated sides of half carcasses were hanged by the tendon of the gastrocnemius (Treatment 1 - T1) and by the pelvic bone (Treatment 2 - T2) in cold store for a 24-hour period. Subsequently, the Semimembranosus muscle was removed from all half carcasses for meat quality analyses. The Semimembranosus muscles from the carcasses hanged by the pelvis suspension method presented higher softness than the same muscles from the carcasses hanged by the tendon of the gastrocnemius, with values of 1.99 kgf.cm-2 and 3.15 kgf.cm-2, respectively. Treatment 2 presented lower meat cooking losses than Treatment 1, with average values of 32.14 and 33.44%, respectively. The remaining meat quality parameters evaluated were not influenced by the carcass suspension method. We concluded that the carcass suspension method influenced meat softness and losses by cooking, with better results for carcasses hanged by the pelvic bone.

Consumer preferences of genetically modified foods of vegetal and animal origin in Chile

Given the debate generated by Genetically Modified (GM) foods in developed and developing countries, the aim was to evaluate the importance of determining factors in the preference of consumers in Temuco and Talca in central-southern Chile for GM foods using conjoint analysis and to determine the existence of different market segments using a survey of 800 people. Using conjoint analysis, it was established that, in general, genetic modification was a more important factor than either brand or price in the consumer's decision to purchase either food. Cluster analysis identified three segments: the largest (51.4%) assigned greatest importance to brand and preferred genetically modified milk and tomato sauce; the second group (41.0%) gave greatest importance to the existence of genetic manipulation and preferred non-genetically modified foods; the smallest segment (7.6%) mainly valued price and preferred milk and tomato sauce with no genetic manipulation. The three segments rejected the store brand and preferred to pay less for both foods. The results are discussed based on studies conducted in developed and developing countries.

Effect of postharvest temperature on the shelf life of gabiroba fruit (Campomanesia pubescens)

The objective of this study was to determine the optimal temperature for storing gabiroba fruit (Campomanesia pubescens) without affecting compounds' quality. The fruits were stored at different temperatures (0 ºC, 6 ºC, 12 ºC, and 20 ºC) and the effect on the pH, total titratable acidity, soluble solids, total sugars, vitamin C, and antioxidant components such as tannins and total phenolic compounds was evaluated. It was observed an increase in the pH and total titratable acidity during storage at all the temperatures tested. Gabiroba fruits were stored for 9 and 3 days at 12 ºC and 20 ºC, respectively, and under both temperatures they showed a reduction in tannins and an increase in vitamin C content. As gabirobas armazenadas a 0º and 6 ºC alcançaram maior tempo de armazenamento After 12 days of storage, the fruits stored at 6 ºC contained higher amounts of water soluble solids, sugars, and antioxidants. In general, for long term storage, it is suggested to store gabiroba fruits at 6 ºC. On the other hand, for short term storage, the temperature of 12 ºC would be the better to keep high levels of vitamin C and phenolic compounds.

Changes in the physicochemical and microbiological properties of frozen araça pulp during storage

Araça belongs to the Myrtaceae family and is popularly known as araçá-comum, araçá-azedo, or araçá-do-campo. Frozen fruit pulp is of great importance for the food industry, which can produce it at the time of harvest, store it, and use it according to the demand of the consumer market and/or as an ingredient in the formulation of products such as yogurt, candies, and ice creams among others. The aim of this study was to evaluate the physical, chemical, and microbiological stability of frozen araça pulp during 12 months of frozen storage. It was observed that the levels of moisture (90.55-88.75%), ash (0.34-0.26%) total soluble sugars (7.11-6.62%), sucrose (3.55-1.39%), soluble pectin (0.24-0.23%), total pectin (0.5-0.46%), pH (3.82-2.31%), organic acids (698.12-122.25 µg.g-1 citric acid), and phenolic compounds (6.22-0.00 mg GAE.100 g-1) decreased during storage, whereas the levels of protein (0.61-0.83%), lipids (0.14-0.38%), total carbohydrates (8.36-9.78%), calorific value (37.14-45.86 kcal.100 g-1), reducing sugars (3.51-5.21%), soluble solids (5.17-6.0%), total antioxidant capacity (6.89-35.13%), and color parameters (L*49.75-50.67; a*0.79-1.82 and b*22.5-25.19) increased over the one-year storage period. According to the chemical and microbiological parameters assessed, the product can be stored for 12 months without loss of quality with addition of citric acid as a preservative.

Stromal interaction molecule 1 and its role in the regulation, proliferation and protein expression in follicular ML-1 thyroid cancer cells

Calcium (Ca2+) is involved in the regulation of variety of cellular functions including hallmarks of cancer development such as cellular migration and cellular proliferation. Store-operated calcium entry (SOCE) is a central mechanism in cellular calcium signaling and in maintaining the cellular calcium balance. Stromal interaction molecule 1(STIM1) has been identified as an important constituent of SOCE. In this thesis , the STIM1 proteins are studied for their importance in cellular processes and their effects on the expression of S1P1, S1P2, S1P3, VEGFR-2, and TRPC-1 in follicular ML-1 thyroid cancer cells. The results show the importance of STIM1 proteins in SOCE in these cells. The SOCE is significantly reduced in the STIM1 knockdown cells. The results also show the importance of STIM1 proteins in the expression of S1P2 and VEGFR-2 in these cells, as knockdown of STIM1 was shown to upregulate the expression of S1P2 and VEGFR-2. The migration and proliferation is also considerably reduced in the cells in which STIM1 has been knocked down showing the significance of STIM1 in the migration and proliferation in these cells.

Optimization of PV and battery capacity for domestic purposes

The usage of PV batteries nowadays became more and more widely spread. Due to the fact that the efficiency of modern PV is rising every year the prevalence of this source of energy is increasing. As the source of the energy is sunlight, these batteries need to be complimented by storage capacitors which will store energy for future use. Nevertheless the less the calculation of demanded amount of energy according the load and capacity of a storage battery that will keep the end consumer in work during certain time still is not overviewed. In this thesis the overall system will be considered and there will be made economic calculations for configurations of such system that will depend from the load. Also the behavior of the system in different geographical and climate conditions that influence of the amount of energy produced will be overviewed.

Visual Customer Segmentation and Data Exploration with the Self-Organizing Map

Advancements in information technology have made it possible for organizations to gather and store vast amounts of data of their customers. Information stored in databases can be highly valuable for organizations. However, analyzing large databases has proven to be difficult in practice. For companies in the retail industry, customer intelligence can be used to identify profitable customers, their characteristics, and behavior. By clustering customers into homogeneous groups, companies can more effectively manage their customer base and target profitable customer segments. This thesis will study the use of the self-organizing map (SOM) as a method for analyzing large customer datasets, clustering customers, and discovering information about customer behavior. Aim of the thesis is to find out whether the SOM could be a practical tool for retail companies to analyze their customer data.

Improving productivity by developing knowledge management practices for a consulting company

The objective of the research was to identify knowledge conversion states in consultancy sales and delivery processes for the company’s one business unit, to know where to store certain types of information and knowledge, and to create best practices for the company’s knowledge management activities in the selected business processes. The used research methodology was action research. The current business processes were analyzed by interviewing people involved in them. The results were documented and catego- rized, and based on them the target states of the processes were developed. Knowledge man- agement activities were integrated to the business processes. The main findings of the research were that roles and responsibilities in the processes were not clear to people, information systems did not fully support individuals and time was wasted searching for information and knowledge. There were also many variations of how the processes actually realized, which affected the overall quality of the process. The conclusions of the research were that knowledge management activities should be high- lighted in businesses where knowledge workers are the main assets of the company. Knowledge management practices can be supported by company culture, leadership and in- formation systems. However, one main factor is each individual’s willingness to share knowledge. By integrating knowledge management activities to business processes and hav- ing information systems supporting knowledge management, individual productivity can be improved.

Adoption and Usability of Online Pharmacies for Purchasing Prescription Medicines

The study examines customers’ perceptions of purchasing prescription medicine from online pharmacies. The main purpose is to find determinants affecting the adoption of online pharmacies, and to consider the role of usability in the adoption process. The theoretical part of the paper provides the overlook on adoption constructs and their relations. In addition, usability factors used in prior studies are presented, as well as how they have been connected to IS adoption research. The specialties of Finnish pharmacy business and the requirements set to online pharmacies are also discussed. The empirical part of the study is conducted with the qualitative approach. Four respondents were interviewed and observed while they tried online pharmacies. The data gathered indicates respondents’ initial beliefs toward the service, perceptions of the usability, and the changes in the perceptions and beliefs after using online pharmacies. The results indicate that usability factors and adoption determinants are interrelated. Usability influences perceived ease of use, which affects both perceived usefulness and behavioral intention. Regulations restrict the design of online pharmacies, which has affect on the both the perceived ease of use and perceived usefulness, and thus the whole adoption process.

Globalização e inconversibilidade monetária

The central hypothesis of this article is that in the context of globalization, monetary inconvertibility is a crucial problem of peripheral countries. It begins with a brief review of the debate from a historical point of view and then stresses the contemporary opposite's views on the fragility of financial system of emerging countries: the original sin and the debt intolerance hypothesis. Despite of supporting the first one, the article goes further and explores the domestic implication of inconvertibility. It criticizes the jurisdicional uncertainty proposition showing that an inherent flaw in the store of value of emerging market currencies, derived from original sin is the main reason for de facto inconvertibility and underdevelopment of domestic financial system of these countries.

Marketing a Mobile Application in a Highly Competitive Global Marketplace

The purpose of this research was to study the marketing of mobile applications. The main objective was to find out what are the most efficient ways of marketing to increase the sales for a mobile application within a highly competitive marketplace. The marketplaces, app stores, are studied from the perspective of size, ease of entry, competition and customers and their purchasing process. The study also includes research on what are some of the main marketing methods used in mobile app marketing in general. The study consists of two parts, theoretical and empirical research. Theoretical research was done by studying past scientific research on the chosen subjects. As the subject is very new, the research was also extended to other publications from the field of mobile technology. The empirical part was done through interviews and empirical experiments with a case-company, which were used to answer the main objective of this study. These experiments showed that the chosen methods of mobile app marketing, app store optimization, localization and selected social media marketing activities, created the most sales when used together. Positive results were seen also when the activities were conducted by themselves, but together they were able to push the case company to their all time best results. However the key to succeeding and hitting high positions in the app store rankings would most likely require creating a solid marketing strategy, trying out other marketing activities alongside the ones used here, without forgetting to stay on top of mobile technology trends.
