Technique for Phytase Enzyme Production from Aspergillus niger and its Efficacy for in vitro and in vivo Dephosphorylation of Corn and Soybean Meal

A technique was developed to produce crude microbial phytase (CMPhy) enzyme form Aspergillus niger, with the objective to enhance phytate phosphorus (pP) availability in corn and soybean meal based broiler diets. The results of in vitro experiments showed that CMPhy enzyme was most active at pH 2.0 and 5.0, as it results in the release of about 79.0% to 88.0% inorganic phosphorus (iP) as a percentage of total phosphorus (tP) from ground corn and soybean meal. In vitro pP hydrolysis was 87.14% in ground corn at 40°C and 5.0-5.5 pH after an incubation period of 8 hrs. with a ratio of 1:1 (CMPhy enzyme:substrate). The pP hydrolysis in soybean meal was 81.25% by applying the same conditions as for ground corn except an incubation period of 10 hrs. When CMPhy enzyme was added to low-P diets for broilers the availability of P increased (63.35%) as compared to the diet with normal-P contents (43.31%) supplied by dicalcium phosphate. Similarly P excretion was reduced to 20.04% units by CMPhy enzyme addition to low-P diet than normal-P diet. Microbial phytase addition to low-P diets, without affecting the performance reduced the P excretion in the dropping thus minimising the P pollution hazards.
New Perspectives in Plasticity Theory: Dislocation Nucleation, Waves, and Partial Continuity of Plastic Strain Rate

A field theory of dislocation mechanics and plasticity is illustrated through new results at the nano, meso, and macro scales. Specifically, dislocation nucleation, the occurrence of wave-type response in quasi-static plasticity, and a jump condition at material interfaces and its implications for analysis of deformation localization are discussed.
Extrapallial abscesses associated with chronic bacterial infections in the intensively cultured juvenile Pacific oyster Crassostrea gigas

During a detailed survey of Pacific oyster Crassostrea gigas juvenile health at intensive rearing facilities, an episode of persistent morbidity and mortality occurred over an 8 wk period in 1997. Affected oyster seed were typically between about 1.0 and 2.4 mm in shell height. Abscesses were formed in the extrapallial space resulting from invasion by straight bacterial rods along the inner shell surface. The abscesses contained host cells and bacteria. The infection appeared to be chronic, was associated with relatively low numbers of bacteria cells, and caused alterations of the underlying mantle and abnormal shell deposition. No signs of any other type of Infectious agent were found associated with the lesions. After a chronic time course, 2 outcomes were possible: either the mantle was breached, leading to an overwhelming terminal bacterial infection or, in some cases, host cell debris and bacteria were sequestered by new shell deposition and the infection was resolved. The condition can cause mortality and significant loss of growth in intensively cultured juvenile oysters.
Design of a Monolithic 79 GHz Rectenna with MOTT Diodes

In this paper a concept and first simulation results for a monolithical integrated rectenna on high resistivity silicon with Schottky diodes operating at MOTT operation is presented. Due to the expected low output voltage of the rectenna, a pre-amplification of the output voltage of the rectenna is done using a commercially available gain block. As high resistivity silicon substrate, a common FZ (float zone) substrate was used. The layout of the vertical and lateral design is discussed. The simulation data according to the realized layout are shown. Additionally the mounting of the rectenna and a preamplifier into a DIP package is presented. The monolithical integrated rectenna can be used as a field probe. By building an array out of single rectenna chips, also a detection of the angle can be done.

Nuclear stress placement by Brazilian Users of English as an International Language

Research has revolved around the pronunciation features that are important to guarantee speech intelligibility by users of English as an international language (IL). In light of the importance of nuclear stress placement for successful communication among speakers in the international community (Jenkins, 2000), the present study investigated the way nuclear stress is placed by four Brazilian Portuguese (BP) intermediate users of English when interacting with other BP users of English (as listeners). Participants met in pairs and engaged in a controlled pairwork oral task, which yielded the production of 160 audio-recorded utterances. With the use of Praat , perceptual and acoustic analysis of the dataset were performed in order to examine if nuclear stress was placed as expected according to the discursive contexts set. The analysis revealed that speakers had difficulties in placing the expected nuclear stress at sentence initial, medial, and, surprisingly, final position. Additionally, it was found that for the participants in the present study, signaling both corrective information and information being elicited by means of nuclear stress placement was challenging. This difficulty in placing nuclear stress may compromise the way these speakers’ intent is interpreted when holding interactions in English.
French airborne lidar measurements for Eyjafjallajökull ash plume survey

Abstract. An Ultra-Violet Rayleigh-Mie lidar has been integrated aboard the French research aircraft Falcon20 in order to monitor the ash plume emitted by the Eyjafjallajokul volcano in April–May 2010. Three operational flights were carried out on 21 April, 12 and 16 May 2010 inside French, Spanish and British air spaces, respectively. The original purpose of the flights was to provide the French civil aviation authorities with objective information on the presence and location of the ash plume. The present paper presents the results of detailed analyses elaborated after the volcano crisis. They bear on the structure of the ash clouds and their optical properties such as the extinction coefficient and the lidar ratio. Lidar ratios were measured in the range of 43 to 50 sr, in good agreement with the ratios derived from ground-based lidar near Paris (France) in April 2010 (~48 sr). The ash signature in terms of particulate depolarization was consistent during all flights (between 34 ± 3 % and 38 ± 3%). Such a value seems to be a good identification parameter for volcanic ash. Using specific cross-sections between 0.19 and 1.1 m2 g−1, the minimum (maximal) mass concentrations in the ash plumes derived for the flights on 12 and 16 May were 140 (2300) and 250 (1500) μg m−3, respectively. It may be rather less than, or of the order of the critical level of damage (2 mg m−3) for the aircraft engines, but well above the 200 μg m−3 warning level.
Transcription Factor as Therapeutic Targets for Neurodegenerative Disorders: An Update

The neurodegeneration is process of the progressive loss of structure and/or functions including death of neurons. Many neurodegenerative disorders such as amyotrophic lateral sclerosis (ALS), Parkinson’s, Alzheimer’s, and Huntington’s diseases occurred as a result of neurodegenerative processes. These neurodegenerative diseases are constantly on rise worldwide. Various transcription factors involved in the pathogenesis of neuro-inflammatory degenerative disorders. The involvement of the latent and active transcription factors are the current focus and target for researchers to work in this area of research. The current review is focused on the regulation of various transcription factors as a therapeutic target for these non-curable diseases.
Summer growth rates of corals at Lord Howe Island, Australia

Spatial, temporal and taxonomic differences in coral growth play an important role in the ecology and dynamics of coral reef ecosystems, affecting reef productivity, heterogeneity, and growth. Moreover, climate change poses an increasing risk to the future status of coral reefs with increasing ocean temperature and acidification causing reductions in growth of reef-building corals, if not survivorship. The purpose of this study was to measure the growth rate of six scleractinian corals, Acropora yongei, Isopora cuneata, Pocillopora damicornis, Porites heronensis, Seriatopora hystrix and Stylophora pistillata, at Lord Howe Island, Australia's southernmost coral reef environment, during the 2010-11 summer growing season. Measurements were taken to compare growth rates of corals from other sub-tropical locations, and greatly increase understanding of the effects of climate change on coral growth. At high latitude locations (subtropical reefs), coral growth is currently limited by the cool winter temperatures and climate related increases in ocean temperature may extend the summer growing period. Conversely, aragonite saturation declines with increasing latitude and climateinduced ocean acidification may further reduce the capacity for growth of calcifying organisms at the latitudinal limits of reef growth. Coral growth (specifically, linear extension) was measured at North Bay and Horseshoe Reef using i) Alizarin staining, and ii) changes in length of individually tagged branches. Acropora displayed at least two fold higher growth rates, significantly greater than other genera, whereas Pocillopora had the lowest growth rate. There was limited evidence of recent increases in growth rates of corals, rather growth rates of Pocillopora were much lower than expected. While very preliminary, these findings suggest that declining aragonite saturation, which will have most pronounced effects on high latitude reefs, are already offsetting any positive effect of increasing temperature.
Explorations of Strategic Orientation (SO) Dimensions on Small Firm Growth and the Challenge of Resources

The strategy-firm growth relationship has been a problematical one for researchers in spite of the significant conceptual, empirical, and theoretical contributions made in this area. While strategy as a broad term signals the maximization of available inputs for a firm, it is the distinctive choices that are available within strategy formulation, termed as Strategic Orientation (SO) by Venkatraman, that has elicited little consensus. The six dimensions of SO construct, as conceptualized by Venkatraman (1989), are analysis, pro-activeness, riskiness, aggressiveness, futurity, and defensiveness. This paper argues that it is the specific SO dimensions or their combinations that contribute to small firm growth depending upon their context rather than the either or approach advanced by Miles & Snow (1978) & Porter (1980) in their strategy type framework. Increasingly, researchers have stressed the need to integrate SO and Resource Based View (RBV) as the choice of resources is an important pre-requisite for small firm growth. At the same time, small firms are resource constrained and SO is a resource consuming orientation which leaves us with the questions: how do resources impact choice of strategy dimensions in small firms? What would enable small firms to create an effective combination of choice of strategy and resources? Key-Words: Strategic Orientation; Small Firm Growth; Resources; Strategy Choice
Hard to fly the nest: A study of body condition and plumage quality in house sparrow fledglings

Contrary to the nestling phase, the post-fledging phase has been less studied probably because it is challenging to follow the chicks after they fledge. However, this phase is crucial to consider when focusing on the life cycle of individuals be- cause it is associated with new demands: After leaving the nest, individuals have to find their own food and cope with a new set of previously unknown stressors. In this study, we aimed at better understanding how energetically demanding the post-fledging period is in house sparrows Passer domesticus by measuring several indices of a fledgling's state (body condition, fat and muscle scores and plumage quality). If the energetic demands of the post-fledging period are greater than those of the adult life, we pre- dicted that fledglings should be in lower condition and should have a plumage of lower quality relative to adults. Supporting this prediction, the condition and the plumage of fledglings differed dramatically from those of adults. Interestingly, this difference disappeared in autumn. Overall, our results suggest that the post-fledging period is probably one of the most energetically de- manding of the life cycle in this species. Supporting this idea, the resighting probability of fledglings was lower relative to adults. However, resighting probability depends on many factors (mortality, dispersal, habitat use and behaviours) and future studies are necessary to tease apart their relative importance in determining resighting probability (Current Zoology 60 (4): 449-459, 2014).
Modelling data intensive web sites with OntoWeaver Conference or Workshop Item

This paper illustrates the OntoWeaver modelling approach, which relies on a set of comprehensive site ontologies to model all aspects of dataintensive web sites and thus offers high level support for the design and development of data-intensive web sites. In particular, the OntoWeaver site ontologies comprise two components: a site view ontology and a presentation ontology. The site view ontology provides meta-models to allow for the composition of sophisticated site views, which allow end users to navigate and manipulate the underlying domain databases. The presentation ontology abstracts the look and feel for site views and makes it possible for the visual appearance and layout to be specified at a high level of abstraction.
Recommender System Optimization through Collaborative Filtering

The amount of available data is growing on a rapid pace. Due to this, data handling is becoming increasingly important. Netix organised an online competition in 2006 to improve their recommender system. Recommender systems based on collaborative ltering optimize product suggestions based on user preferences by analyzing past user and item rating behaviour. The aim of this research is to optimize movie suggestions by predicting movie ratings based on past ratings. This is done by implementing the neighbourhood based collaborative ltering method described in Bell and Koren
A New Trans-to-Cis Photoisomerization Mechanism of Azobenzene on the S1(n,π*) Surface

The rotation-inversion controversy for the photoisomerization mechanism of azobenzene has been addressed on the basis of the CASSCF calculations for the excited-state relaxed surface scan along the CNN bending (inversion), the CNNC torsion (rotation), and the concerted CNN bending (concerted inversion) reaction pathways. According to our calculated results, the inversion channel involves a substantial energy barrier and a large S0−S1 energy gap so that it is a highly unfavorable channel to be considered for an efficient electronic relaxation. The rotation channel is essentially barrierless with a conical intersection close to the midpoint of the pathway to reasonably account for the subpicoseond to picosecond relaxation times observed in recent ultrafast experiments. Along the concerted inversion reaction path, a sloped conical intersection (S0/S1 CI_inv) was found to have the geometry close to a linear CNNC configuration. When the photoexcitation occurs in the S2 state, the concerted inversion channel ma.
Effects of disorder on the exchange coupling in (Ga,Mn)As diluted magnetic semiconductors

A theoretical study of the effects of disorder on the Mn-Mn exchange interactions for Ga1-xMnxAs diluted magnetic semiconductors is presented. The disorder is intrinsically considered in the calculations, which are performed using an ab initio total energy density-functional approach, for a 128 atoms supercell, and by considering a variety of configurations with 2, 3 and 4 Mn atoms. Results are obtained for the effective J$^{Mn-Mn}_n$, from first (n = 1) all the way up to sixth (n = 6) neighbors via a Heisenberg Hamiltonian used to map the magnetic excitations from ab initio total energy calculations. One then obtains a clear dependence in the magnitudes of the J$^{Mn-Mn}_n$ with the Mn concentration x. Moreover, we show that, in the case of fixed Mn concentration, configurational disorder and/or clustering effects lead to large dispersions in the Mn-Mn exchange interactions. Also, calculations for the ground-state total energies for several configurations suggest that a proper consideration of disorder is needed when one is interested in treating temperature and annealing effects.
The quantitative effects of population density and winter weather on the body condition of white- tailed deer (Odocoileus virginianus) in Nova Scotia, Canada

Understanding the underlying mechanisms that cause variation in survival and the reproductive success of animals is essential for predicting variation in population parameters. To gain an understanding of the effects of density and winter weather severity on white-tailed deer, Odocoileus virginianus (Zimmermann, 1780), we examined the effects of current-year deer density and cumulative weekly average values for snow depth, rainfall, and the number of degrees below -15 °C until the time of death, as well as cumulative effects of density and snow depth over the previous one and two winters, on the body condition of adult females, adult males, and fawns. Model selection using Akaike's Infor- mation Criterion and multi-model inference suggested that snow depth was the best predictor of body condition for all three age/sex groups. Winter rainfall was the next most influential predictor for adult females and adult males but was not important in determining fawn body condition. Temperature had the least influence on the body condition of all three age/sex groups. Deer density during the winter of death had minimal effects for all groups and we found no evi- dence that cumulative multiyear variables influenced body condition. We hypothesize that cohort variation may better explain previous findings showing effects of multiyear variables. A model for estimating the proportion of animals in poor body condition for each age/sex group is presented.
ROLE OF SWISS BALL EXERCISES IN REDUCING PAIN, DISABILITY AND IMPROVING MUSCLE ENDURANCE IN PATIENTS WITH MECHANICAL LOW BACK ACHE

Introduction: Low back pain is a very common health problem associated with considerable disability and costs to society. Low back pain is becoming increasingly common. Approximately 70-90% of our population suffers from low back pain or has suffered from multiple episodes of low back pain. Pain aggravated by extension, sideflexion, rotation, standing, walking, sitting, and exercise in general, and relieved by changing in position. Many different therapeutic interventions are used in the management of low back pain. Swiss ball exercises have become an important part of the fitness regimen and widely used exercises for low back ache.
The influence of interhemispheric connections on ongoing and evoked orientation preference maps and spiking activity in the cat primary visual cortex

A atividade cerebral espontânea exibe padroes que lembram o de coativacao de conjuntos neuronais em resposta a estimulos ou tarefas. Estes padroes tem sido atribuidos a arquitetura funcional do cerebro, e.g. conexoes de longo alcance em patches (manchas, fragmentos). Nos investigamos diretamente a contribuicao destas conexoes em patches entre hemisferios para mapas espontâneos e evocados na area 18 proxima a borda 17/18 de gatos. Registramos mapas com imageamento por votage-sensitive dye (VSD) e atividade despiking enquanto manipulamos o input interhemisferico pela desativacao reversivel das areas correspondentes contralaterais. Durante a desativacao os mapas espontâneos continuaram sendo gerados com frequencia e qualidade semelhante ao da rede intacta, mas um vies de orientacoes cardinais desapareceu. Neuronios com preferencia por orientacoes horizontais (HN) ou verticais (VN), ao contrario dos de preferencia obliqua, diminuiram sua atividade de repouso, no entanto, HN tiveram a atividade diminuida mesmo quando estimulados visualmente. Concluimos que mapas espontâneos estruturados sao primariamente gerados por conexoes talamo- e/ou intracorticais. Entretanto, conexoes de longo alcance pelo corpo caloso - como um prolongamento da rede de longo alcance intracortical - contribui para um vies cardinal, possivelmente porque estas conexoes sao mais fortes ou mais frequentes entre neuronios preferindo orientacoes horizontais e/ou cardinais. Estes contornos sao mais faceis de perceber e aparecem com mais frequencia no ambiente natural, cone xoes de longo alcance podem prover o cortex visual com um grid de operacoes probabilisticas de agrupamento em uma cena visual maior.
Emotional Empathy Model For Robot Partners Using Recurrent Spiking Neural Network Model With Hebbian-Lms Learning

This paper discusses the development of an emotion model for robot partner system. In our previous studies, we have focused only on the robot’s emotional state. However, the emotional state of the other party is also an important factor for smooth conversation in human society. Therefore, the robot partner has two emotional structures for human: empathy and robot emotion. First, human empathy uses a perceptual based emotion model to know the human’s emotional state based on the sensory information. Next, we propose a recurrent simple spike response model to improve the robot’s emotional model, and we apply “Hebbian-LMS” learning to modify the weights in the spiking neural network. The robot’s emotional state is calculated by using the human’s emotional information, internal and external information. The robot partner can use the emotional results to control the facial and gesture expression. The utterance style is also changed by the robot’s emotional state. As a result, the robot partner can interact emotionally and naturally with human. First, we explain the related works and the development of the robot partner “iPhonoid-C”. Next, we define the architecture of the emotional model to realize emotional empathy towards human. Then, we discuss the algorithms and the methods for developing the emotional model. Finally, we show experimental results of the proposed method, and discuss the effectiveness of the proposed structure.
Numerical simulation of magneto-hydrodynamics mixed convection in an open channel having a semi-circular heater

The present study is conducted to investigate heat and fluid flow in an open channel having a circular heater on the bottom surface under magnetic field. The semi-circle is heated isothermally and the other walls of the channel are kept adiabatic. The consequent mathematical model is governed by the coupled equations of mass, momentum and energy and solved by employing Galerkin weighted residual method of finite-element technique. A wide range of pertinent parameters such as Rayleigh numbers ( Ra ), and Hartmann numbers ( Ha ) are considered in the present study. In addition, the mixed convection regime is occurred due to buoyancy and shear forces. Various characteristics such as streamlines, isotherms and heat transfer rate in terms of the average Nusselt number ( Nu av ), average fluid temperature ( θ av ), and Drag force ( D ) is investigated for the aforesaid parameters. The magnetic field is found as a control parameter on heat and fluid flow, particularly at higher Rayleigh numbers. It is observed that Hartmann numbers have a significant effect on average Nusselt number, average fluid temperature and Drag force.
