Molecular and Phenotypic Characterization of Metschnikowia pulcherrima Strains from Douro Wine Region

Some non-Saccharomyces yeasts, including Metschnikowia pulcherrima, have been proposed as selected starters due to their contribution for the overall aroma and chemical profiles of wines. In this work, we aimed to evaluate the genetic and phenotypic diversity of Metschnikowia pulcherrima strains isolated from different locations of Douro Wine Region, and to explore their potential as co-adjuncts of S. cerevisiae in alcoholic fermentation. For that purpose, a set of 64 M. pulcherrima isolates were used. Polymerase chain reaction (PCR) fingerprinting with M13 primers demonstrated to be an efficient tool in intraspecific discrimination of M. pulcherrima strains. No significant associations were found between genotypic profiles and either geographical origin or winery. The isolates were screened for their stress resistance ability (ethanol, SO2, chitosan, copper, H2O2, and Grape Juice Medium), aroma-related activities (resistance to 5, 5′, 5′′-trifluor-d, l-leucine and cerulenin and β-glycosidase, β-lyase and sulfite-reductase activities) as well as other relevant technological proprieties (protease activity and biogenic amines production). M. pulcherrima response to the different enological traits evaluated was greatly strain-dependent. The most discriminant features were the ability of the strains to grow in Grape-Juice Medium (GJM) and sulfite-reductase, and their β-lyase and protease activities. The enological potential of a selected M. pulcherrima strain in mixed-culture with S. cerevisiae was also assessed in natural grape-juice of a local variety, under two nitrogen regimes. M. pulcherrima proved to be promising for future industrial application as a co-starter, lowering ethanol, acetic acid and, reported here for the first time, lowering hydrogen sulfide levels in the wines.

A review of literature on evaluating the scientific, social, and political impact of social sciences and humanities research

Recently, the need to contribute to the evaluation of the scientific, social, and political impact of Social Sciences and Humanities (SSH) research has become a demand of policy makers and society. The international scientific community has made significant advances that have transformed the impact of evaluation landscape. This article reviews the existing scientific knowledge on evaluation tools and techniques that are applied to assess the scientific impact of SSH research; the changing structure of social and political impacts of SSH research is investigated based on an overarching research question: to what extent do scholars attempt to apply methods, instruments, and approaches that take into ac-count the distinctive features of SSH? The review also includes examples of European Union (EU) pro-jects that demonstrate these impacts. This article culminates in a discussion of the development of the assessment of different impacts and identifies limitations, and areas and topics to explore in the future.
Strategic Perils of Outsourcing: Sourcing Strategy and Product Positioning

Although outsourcing input production has long been considered as an important approach to help downstream manufacturers enhance structural efficiency, we provide a theoretical explanation for why outsourcing may negatively affect downstream firms' profitability. We consider a duopoly model wherein downstream manufacturers endogenously determine their input sourcing and product positioning strategies. We show that when inputs from outside suppliers are not perfectly compatible with downstream manufacturers' requests, outsourcing causes downstream manufacturers to pursue aggressive product positioning behavior, leading to the prisoner’s dilemma --- even though both downstream manufacturers could be better off producing inputs in-house, they may still choose outsourcing.
Snapper Pagrus auratus (Sparidae) home range dynamics : acoustic tagging studies in a marine reserve

The home-range size and location of reef-associated snapper Pagrus auratus: Sparidae were investigated by use of a radio acoustic-positioning telemetry (RAPT) system. Tags were surgically implanted in 5 snapper that were subsequently monitored every minute for a period of 5 mo, and then intermittently over another 7 mo. Site fidelity was high amongst these fish, with home ranges not exceeding 650 m in diameter or 139 600 m2 in area. Eleven other snapper received tags by feeding and were tracked for periods of up to 2.5 d. Site fidelity was also high for these fish, with standardised estimates of home-range size not differing between the 2 groups. Home ranges overlapped considerably, indicating that the fish were not territorial. The location of the home ranges generally remained stable throughout the entire tracking period, although 1 fish relocated its home range by ~220 m. A new method of home-range estimation was developed, which matched the level of detail provided by the RAPT system, to directly estimate the time spent in an area. The relevance of this method and the residential behaviour of these fish are discussed, with reference to the general understanding of animal behaviour, previous investigations into snapper movement, and the selective capacity that may be imposed by marine reserves on fish behaviour.
Subsurface arsenic removal column tests: from the laboratory to the field

Previous laboratory column experiments have given evidence of competitive effects between different groundwater constituents in the process of subsurface arsenic removal, a process in which arsenic is removed from groundwater by injecting water with oxygen into the subsurface. The presence of phosphate and other anions significantly limited arsenic removal. To investigate the influence of phosphate in natural groundwater, pumping stations in Loosdrecht (the Netherlands) and Subotica (Serbia) both with low phosphate concentrations ( −1 ) and considerable arsenic concentrations (30 and 110 μg l −1 ) were chosen, to perform experiments identical to the previous laboratory work. Despite of the absence of phosphate, the subsurface arsenic removal process performed poorly in Subotica, with 50% arsenic breakthrough occurring after 2 to 4 column pore volumes of abstracted water. In Loosdrecht subsurface arsenic removal showed more promising results, 50% breakthrough after 6 to 7 pore volumes, while having a lower pH than Subotica and similar silicate concentrations. The water composition of both locations gives reason to suggest that natural organic matter has a limiting effect on subsurface arsenic removal as well. The presented results have shown the complexity of factors influencing subsurface arsenic removal, making it very challenging to select appropriate sites.
Money demand function for Malawiimplications for monetary policy conduct

This paper analyzes the money demand function for Malawi during the period of 1985-2010 using monthly data. During the sample period, several structural changes occurred in the economy. Most of these changes were ignited by the structural adjustment programs that started in the late 1980s, then came the move to plural politics in the early 1990s. This was followed by structural reforms in the financial sector. In the very recent past, there has been an increase in real economic activity as measured by strong growth in real GDP in the years after 2002 and the financial innovations within the banking system after the year 2000. These factors do not seem to have affected the stability of the demand for money and hence increasing the probability of success for the conduct of monetary policy. Cointegration test results indicate a long-run relationship amongst real money balances, prices, income, exchange rate, Treasury bill rate and financial innovation. While all variables significantly influence money demand in the long-run, short-run policy must be directed at increasing financial innovation, open market activities and improving the productivity of the economy to provide higher return on alternative investments.
Grandparents raising grandchildren: investigating factors associated with distress among custodial grandparent

The aim of the current study was to explore the relationship between the psychological health of grandparents raising grandchildren, and those grandchildren's social, emotional and behavioural issues. The study also assessed the relationship between psychological well-being in grandparents and access to informal social support. The sample comprised 100 grandparents who were raising grandchildren. Regression analyses revealed that grandparents caring for grandchildren with abnormal emotional and hyperactive symptoms scored higher on measures of anxiety, stress, and depression, and were more likely to report less life satisfaction. Grandparents with greater access to informal support experienced less depression, although greater access to informal social support did not lessen the impact of raising grandchildren with social, emotional, or behavioural issues. Implications for intervention and policy are discussed.
The Construction of Oral Problems in an EFL Context: An Innovative Approach

How are oral problems constructed in English as a Foreign Language (EFL) communication? Oral communication problems can be major challenges to effective foreign language learning and communication. This paper investigates the nature of oral problems in foreign language learning and communication in order to provide a means of being more familiar with the complexities of problem-construction in an EFL context. Using theories of interpersonal communication, I introduce a novel approach for rethinking the issue of language use and context with foreign language learners. Adopting a qualitative research approach, I collected data from a series of interviews with a group of language teachers and Persian learners of English Literature and Translation. Analysing interview data allowed me to capture the viewpoints of participants with respect to how they perceived their problems in L2 oral communication. The findings challenge stereotypes about lack of language knowledge always being responsible for oral problem in L2 communication. I conclude that oral problems are also mediated by participants’ construction of self, others and by the context of L2 communication.

Behavior and Flexural Prediction of Special Cementitious Bonding Material for Fiber Reinforced Strengthening Systems

Strengthening of RC structures with externally bonded FRP (fiber reinforced polymers) has become an important challenge in civil engineering. Epoxy is the main bonding agent used so far, but in the case of a fire, it is subjected to complete loss of his bonding capabilities. Mineral based composites strengthening systems consist of FRPs and a cementitious bonding agent which form a repair or strengthening system that is more compatible with the concrete substrata, and roved its efficiency. The current research introduces the use of a special cementitious material “Grancrete” as a bonding agent. Test results of 32 T-section RC beams strengthened with various FRG (fiber reinforced Grancrete) strengthening systems are presented. The results demonstrated that most of the specimens were likely to fail by debonding of the FRP from the concrete either at the ends or at intermediate flexural cracks. This paper presents an in-depth study aimed at the development of a better understanding of debonding failures in RC beams strengthened with externally bonded FRP systems. Different analytical models, published in the literature for plate end debonding, are reviewed and compared to test results. The results also demonstrated that when using U-wraps, the specimens were likely to fail by FRP sheet rupture.
Design Issues for Claw Pole Machines with Soft Magnetic Composite Cores

By using global ring winding, the torque coefficient of the transverse flux machine (TFM) is proportional to its number of pole pairs, and thus the TFM possesses high torque density ability when compared with other electrical machines. As a special kind of TFM, the claw pole machine (CPM) can have more torque due to its special claw pole teeth. The manufacturing of CPM or TFM with silicon steels was very difficult in the past, and is a handicap for the progress of this kind of machine. Thanks to the advent of soft magnetic composite (SMC) materials, the manufacturing process of CPM has become more and more simple. More attention has been paid to this kind of technology, and some mass production CPMs with SMC cores have appeared. However, there are few works that discuss the key design issues for this kind of machine. In this paper, a small CPM with SMC is used as as a research benchmark. Various design methods that can be adopted to improve its performance have been studied, including unequal stator claw pole teeth, a skewing magnet design, consequent pole design, and etc. The 3D finite element method (FEM) is used for the machine analysis, and it is verified by the experimental results of a CPM with SMC cores.
Disk harrow operational performance in three engine rotation speeds

Even with the current techniques of conservation tillage, mobilization is still a widely used practice, either in initial preparation as in reform of agricultural areas. In this context the harrows are widely used, mainly because of the good working capacity and high efficiency in tillage soil. Thus, this study aimed to evaluate the operating performance of a disc harrow in clay soil using different spins. The experiment was conducted at the Experi­mental Farm Lageado, belonging to the Faculty of Agricultural Sciences - UNESP Botucatu - SP. For accomplishment of the tillage was used a disk harrow, mark Tatu Marchesan model GAICR off-set, with a cutting width of 2.57 m and consists of 20 cut disks of 0,71 m (28 inches) spaced at 0.27 m. To exert traction the disk harrow was used of tires tractor John Deere brand, model JD6600 with power 91.48 kW (121 hp) engine. The used treatments were three engine revolutions, 157 rad s -1 (1500 rpm), 189 rad s -1 (1800 rpm) and 220 rad s -1 (2100 rpm), and evaluated the working speeds achieved, effective field capacity, operational fuel consumption, working depth of the disc harrow, skating wheels of the tractor and drawbar force. The results indicated that most job rotation provided lower fuel consumption and greater field capacity. However, the increase in speed of work provided a reduction of working depth of the discs of the harrow.
STRATEGIC LEADERSHIP , RESOURCE MANAGEMENT AND EFFECTIVE SCHOOL REFORM

This paper explores the impact of school reform on learning outcomes and on the professional culture of the principalship. The report draws on findings from several research projects involving surveys and case studies in the period 1993 to 1998, with special focus on the Schools of the Future reform in Victoria, Australia. The article describes the research programs used in the study, and offers an account of the emerging roles and preferences of principals for the new organizational arrangements. A description of new mechanisms for the management of resources sets the scene for a review of findings on learning outcomes. The final section describes the professional culture of the principalship that is emerging under these conditions. The findings show that despite several dysfunctions, unfulfilled expectations, and intensification of work, a large majority of principals would not return to previous organizational governance. Structural equation modeling of the sources used in the study revealed a stable pattern of direct and indirect effects of reform elements on learning outcomes for students. Case studies revealed that principals played an important role in helping link the structural aspects of reform to learning and teaching. Leadership was strategic and empowering more than it was heroic or "hands on. " (Contains 42 references.)

A Local Localization Algorithm based on WSN

After studying the topological structure of neighboring nodes in the WSN, we present a local localization (LLA) algorithm by combining the ideas of principal manifold learning and nonlinear dimension algorithm. This algorithm is particularly suitable for determining the relative locations of sensor nodes in the large-scale and low-density WSNs, where the low connectivity between nodes and the large ranging error between long-distance nodes usually make accurate localization quite difficult. In this algorithm, based on the pair-wise distance between each node and its neighbor nodes within a certain communication range, the local geometry of the global structure is firstly obtained by constructing a local subspace for each node, and those subspaces are then aligned to give the internal global coordinates of all nodes. Combined with the global structure and the anchor node information, we can finally calculate the absolute coordinates of all unknown nodes in the least squares algorithm.
Regular(Ized) Hedge Fund Clones

This article addresses the problem of portfolio construction in the context of efficient hedge fund investments replication. We propose a modification to the standard a la Sharpe ‘style analysis’ where we augment the objective function with a penalty proportional to the sum of the absolute values of the replicating asset weights, i.e. the norm of the asset weights vector. This penalty regularizes the optimization problem, with significant impacts on the stability of the resulting asset mix and the risk and return characteristics of the replicating portfolio. Our results suggest that the norm-constrained replicating portfolios exhibit significant correlations with their benchmarks, often higher than 0.9, have a fraction, i.e. about 1/2 to 2/3, of active positions relative to those determined through the standard method, and are obtained with turnover which is in some instances about 1/4 of that for the standard method. Moreover, the extreme risk of the replicating portfolios obtained through the regularization method is always lower than that exhibited by currently available commercial hedge fund investment replication products.
