Physicochemical composition, minerals, and pesticide residues in organic grape juices

Demand for organic products is intensified in many countries each year. Following this trend, Brazil produces increasing volumes of organic grape juice. In this way, a survey of organic grape juices made from grapes produced according to this system was carried out where physicochemical composition, minerals, trace elements, and pesticide residues were determined. Variables related to grape juice composition were performed by physicochemical procedures; minerals and trace elements, by inductively plasma optical emission spectrometry; pesticide residues, by liquid chromatography-mass spectrometry. Main results show that the physicochemical composition of organic grape juices was in general in accordance to the Brazilian legislation. The mean concentrations of trace elements were very low, varying from 0.002 (Cd) to 0.970 (Ba) mg L–1. Pesticide residues were not detected in any sample analyzed (MRL= 10 µg L–1). These results show that the Serra Gaúcha viticultural region present conditions to produce organic grape juices, despite the adverse climate factors that occurs in some years. Nevertheless, these products should be made with grape varieties, such as the labrusca ones, less susceptibles to the main grapevine pathogens.

Impact of different drying parameters on color, β-carotene, antioxidant activity and minerals of apricot (Prunus armeniacaL.)

Abstract Apricot is one of the fruits dried by using different methods, such as sun, convective or microwave drying. The effects of drying methods on the components of this fruit differ depending upon the temperature or time parameters. In this research, the impacts of convective, microwave and microwave–convective drying techniques on color, β-carotene, minerals and antioxidant activity of apricots were investigated. The color values (L*, b*,ΔEab, h° and C*ab) of dried fruit were decreased, while the a* values increased. Compared with a fresh sample, the dried apricots showed a 1.4-3.9-fold proportional increase in β-carotene based on the increment of dry matter. The samples dried at high temperature and microwave levels, at 75 °C+90 watt and 75 °C+160 watt, showed lower antioxidant activity. Of the different drying treatments, the microwave-convective method (50 °C+160 watt) obtained a higher β-carotene content while maintaining antioxidant activity with a short drying time.

Designing gamification for collaborative learning in group work

Computer Supported Collaborative Learning (CSCL) is a teaching and learning approach which is widely adopted. However there are still some problems can be found when CSCL takes place. Studies show that using game-like mechanics can increase motivation, engagement, as well as modelling behaviors of players. Gamification is a rapid growing trend by applying the same mechanics. It refers to use game design elements in non-game contexts. This thesis is about combining gamification concept and computer supported collaborative learning together in software engineering education field. And finally a gamified prototype system is designed.

Performance improvement in mediterranean operations using risk management analysis : Case study of Containerships Group Ltd

Emerging markets of Northern Africa and Turkey provide growth opportunities for logistics service companies in the middle of low growth environment of European Union. The purpose of this research is to explore and analyze the risk factors in container shipping industry and third party logistics (3PL) services. The research empirically examined the risk factors, which are related within the interaction between these two parties in emerging markets of Mediterranean area. The previous studies have provided a valuable insight into the operational risks faced by container shipping industries. However, most of these studies have focused on one or several operational risk factors from a single point of view, and no studies have inclusively examined the possible operational risks faced in the container shipping industry from dual perspective of 3PL provider and its customers. A questionnaire has been deployed to collect related data; and the impacts of the risks were then be assessed and ranked using the method of risk mapping. Respondents were located in Turkey, Algeria, Tunisia, and Libya. Research presents the most important risk factors identified, and compares them between 3PL provider and its customers. The research also provide some risk mitigation strategies for the key risk factors, and tried to figure out a common risk picture, which guides the managers in both sides to have a better decisions and as a result, improve the performance of the container shipping operations. Challenge during project execution time was that customers identified vast amount of more risks than what was the case with logistics service operator.

Saksan graniittimarkkinoiden analysointi: Case Ylamaa Group Oy

Tämän kandidaatintyön tavoitteena on analysoida Saksan graniittimarkkinoiden houkuttelevuutta suomalaisen yrityksen näkökulmasta. Ylamaa Group Oy on rakennus-, ympäristö- ja sisustuskiveä tuottava yritys, joka on jo toimittanut Saksan alueelle tuotteitaan, mutta toiminta on ollut siellä vielä varsin vähäistä. Saksaa markkina-alueena analysoidaan PESTEn, sekä talouden ja maan raken-nusalan tulevaisuudennäkymien avulla, kilpailuasetelmaa puolestaan Porterin viidellä voimalla. Lisäksi tutkitaan asiakkaan kokemia arvoja graniitin tapauksessa ja etsitään yhteyksiä niiden, ja case-yrityksen ydinosaamisten välillä. Näin osoitetaan, miten yritys voi luoda itselleen kilpailuetua. Työn tuloksena käy ilmi, että Saksan markkinoille kannattaa laajentua. Kuitenkin kilpailu Saksassa on kovaa Euroopan yhtenäisen talousalueen vuoksi. Ylamaa Groupin tuleekin ottaa tuotannossaan ja markkinoinnissaan huomioon erinäisiä seikkoja Saksan markkinoilla pärjätäkseen, kuten hinta-laatusuhteen ja ympäris-töystävällisyyden korostamista.

The research topic of the work is: “Factors of innovation creation within functionally heterogeneous project teams”. The research question is “What are the factors of innovation creation within functionally heterogeneous project teams?” The subject of this research is to explore the teams of projects, aimed at creating innovations, and understand how innovation is generated through project team work within them in term of factors. In line with the purposes of this study, firstly, it was analyzed what factors of such teams’ work are affecting creating innovation positively and negatively on the base of chosen literature and a preliminary conceptional framework was formulated, and secondly, the research of the work of project teams in one of the divisions of ABB company has been done and other factors and interdependencies between them have been added to the conceptional framework. This final conceptional framework constitutes the essense of the work findings and can be used as a tool to analyze the innovation creation process in functionally heterogeneous project teams

NEGOTIATING IN FINNISH GROCERY RETAIL - Negotiation Narratives of S-group, Kesko and Lidl

In this research retail negotiations are explored through the question: What characteristics are distinctive to negotiating in Finnish grocery retail trade? To shed light on the research question I interviewed experienced retail negotiators and mapped out the most important characteristics of the retail negotiations. I described through examples the most prominent challenges negotiators face in their negotiations and elaborated what kind of tools the experienced negotiators use to overcome those challenges. The research results add up to a groundwork frame for retail negotiations with which further research can be more easily directed to any area of interest in the Finnish grocery retail negotiations. The framework can give ideas or frames for further research, or function as a general guideline of factors to consider when negotiating in Finnish retail field. The results were divided into 3 sections: Characteristics, Challenges and Tools. Different negotiation models help negotiators and researchers understand negotiation dynamics. This research adds to that pool by focusing on elements essential to consider specifically in the context of Finnish retail. Finland offered an exceptionally interesting setting to study negotiation, as grocery retail trade in Finland is highly centralized. Especially for those interested understanding a centralized setting such as Finland’s retail field, the framework presented in this research might provide a valuable spectrum of essential negotiation elements. Learning is a lifelong process, but that path can be evened by tuning in on what others have learned during their own endeavors in similar situations. Seasoned negotiators have many stories to tell about negotiating that can be drawn upon and by doing so, we can avoid having to spend time learning the same insights twice. This research drew on narrative, case-research and interviewing to find out how seasoned negotiators in the field of Finnish retail experienced negotiation, what challenges negotiations pose and what tools can be used to overcome them
