Diet and bioclimatic conditions on production and milk quality.

It was aimed to analyze the productive performance of lactating cows on isoprotein fed diets, at differentiated environmental conditions. Eight Holstein cows were used, grouped in two 4 × 4 balanced Latin squares design. The treatments were evaluated in 2 × 2 factorial designs: sources of roughage (corn silage – CS plus concentrate, and the combination of corn silage with sugarcane - CSSC, 1:1 on DM, plus concentrate) and distinct environment (with= WS and without= OS, fan and nebulizers system= Sfn). The estimation of dry matter intake (DMI), productive performance and physicochemical parameters of milk were evaluated. There was no interaction effect of environment factors and source of forage. There was signiA cant effects for the source forage factors, where the DMI for the CSSC based diet was higher than the CS based diet in the effect of forage (4.22 vs. 4.06% BW, and 22.3 vs. 21.7 kg/d, respectively, P≤0.05), but with similar milk production correcting 3.5% fat (23.01 vs. 22.62, CSSC and CS; 22.85 vs. 22.78 kg/day, WS and OS, respectively, P≥0.05). The feed efA ciency and conversion was similar in both factors (102.8 vs. 104.7% and 0.99 vs. 1.0, CSSC and CS; 102.5 vs. 104.9% and 1.0 vs. 0.99, WS and OS, respectively, P≥0.05). The beneA t-diet cost ratio was higher for CS-based diet than for CSSC (7.44 vs. 6.97, P≤0.05). There were effects only in the forage factor for CP milk (3.26 vs. 3.23%, P≤0.05), lactose (4.54 vs. 4.49%, P≤0.05) and urea nitrogen in milk (23.21 vs. 20.71 mg/dL, P≤0.05) and the superiority arising from the CSSC-based diet in comparison to the CS diet. There was higher for T and THI (28.1 vs. 23.6°C and 75.1 vs. 71.1, respectively, P≤0.05), and lower RH to 2:00 pm (47.7 vs. 64.5%, P≤0.05). The linear score showed negative correlations with DMI, milk production, lactose and urea nitrogen (-0.36, -0.69, -0.44 and -0.32, P≤0.05, respectively). The use of the diet based on CSSC proposed increases in DMI and milk quality without affecting production, but with smaller beneA t-diet cost ratio. The use of the environmental cooling system did not improve the production, qualitative parameters of milk and thermal comfort of dairy cows under the conditions evaluated.
Continuous-time duality for superreplication with transient price impact

We establish a super-replication duality in a continuous-time financial model where an investor's trades adversely affect bid- and ask-prices for a risky asset and where market resilience drives the resulting spread back towards zero at an exponential rate. Similar to the literature on models with a constant spread, our dual description of super-replication prices involves the construction of suitable absolutely continuous measures with martingales close to the unaffected reference price. A novel feature in our duality is a liquidity weighted $L^2$-norm that enters as a measurement of this closeness and that accounts for strategy dependent spreads. As applications, we establish optimality of buy-and-hold strategies for the super-replication of call options and we prove a verification theorem for utility maximizing investment strategies.
Assessing the Relationship Between Entrepreneurial Orientation, Reputational Resources and Absorptive Capability: A Resource-Based Approach

Building on well established theories, our research explores the influence of entrepreneurial orientation on reputational resources and absorptive capacity of knowledge exploitation of Portuguese small and medium enterprises (SMEs) of footwear associated to the Portuguese Footwear, Components and Leather Goods Association (APICCAPS). Therefore, a quantitative methodological approach was used, conducting a descriptive, exploratory and transversal empirical study, having applied a questionnaire to a sample of Portuguese SMEs. Based on survey data from 42 firms, our empirical results indicate that globally entrepreneurial orientation have a positive and significant influence on knowledge exploitation and that the entrepreneurial orientation’s dimensions that most contribute to this end are innovation and risk-taking. Moreover, the processes for exploitation of reputational resources and knowledge became an essential element for firms to adapt to changes in the competitive environment. The exploitation of this resources and capacities should be undertaken with innovation, proactivity and risk-taking.
Safety of the navigation in congested maritime area. the case of the Messina Strait

In the last decade a relevant expansion of traffic by sea occurred, not only on the long distances, but also on the middle-short distances; on coastline urban areas and particularly on neighboring urban areas, but separated by the sea, the increase of the flows often involves greater risks of accident for the navigation (Lewison, 1978; Merrick et al., 2001; van Dorp et al., 2001). The risk of maritime accident results particularly high for the ro-ro ships. This paper clarifies some aspects concerning the concept of risk and safety at sea dealing with some literature models. An application is proposed to the Messina Strait context that is the crossroad of elevated flows of traffic along two directions. The navigation safety in the Messina Strait has been analyzed with the support of a micro-simulation approach.
A general correspondence between dual minimax problems and convex programs

The Kuhn-Tucker theory of Lagrange multipliers centers on a one-to-one correspondence between nonlinear programs and minimax problems. This correspondence has been extended by Dantzig, Eisenberg and Cottle to one in which every minimax problem of a certain type gives rise to a pair of nonlinear programs dual to each other. The aim here is to show how, by forming conjugates of convex functions and saddle-functions (i.e. functions of two vector arguments which are convex in one argument and concave in the other), one can set up a more symmetric correspondence with even stronger duality properties. The correspondence concerns problems in quartets, each quartet being comprised of a dual pair of convex and concave programs and a dual pair of minimax problems. The whole quartet can be generated directly from any one of its members.
Performance of Antenna Selection in MIMO System Using Channel Reciprocity with Measured Data

The channel capacity of MIMO system increases as a function of antenna pairs between transmitter and receiver but it suffers from multiple expensive RF chains. To reduce cost of RF chains, antenna selection (AS) method can offer a good tradeoff between expense and performance. For a transmitting AS system, channel state information (CSI) feedback is required to choose the best subset of available antennas. However, the delay and error in feedback channel are the most dominant factors to degrade performances. In this paper, the concept of AS method using reciprocal CSI instead of feedback channel is proposed. The capacity performance of proposed system is investigated by own developing Testbed. The obtained results indicate that the reciprocity technique offers a capacity close to a system with perfect CSI and gains a higher capacity than a system without AS method. This benefit is from 0.9 to 2.2 bps/Hz at SNR 10 dB.
Field emission - based many-valued processing using carbon nanotube controlled switches - Part 2: Architecture effectuation

A novel field emission Carbon Nanotube (CNT) - based controlled switch is introduced in the second part of the article. For the architecture effectuation of the new CNT field emission - based switching device, four field emission tubes having single CNT as emitters were previously tested and compared to a tungsten-tip tube, and the corresponding Fowler-Nordheim analysis was performed. Measurements conducted with the CNT suggested that mixer current could be 30 times greater if either SWCNT or MWCNT were used in place of metal emitters, increasing the microwave output power by 30 dB. Laser radiation was utilized to increase field emission current from a cathode with a dense field of CNT by a factor of 18. The extension of the new device from the two-valued to the general m- valued case is introduced, and the implementation of many-valued Galois circuits and systems is also shown.
Managing Micro Vms in Amazon Ec 2

Micro instances (t1.micro) are the class of Amazon EC2 virtual machines (VMs) offering the lowest operational costs for applications with short bursts in their CPU requirements. As processing proceeds, EC2 throttles CPU capacity of micro instances in a complex, unpredictable, manner. This thesis aims at making micro instances more predictable and efficient to use. First, we present a characterization of EC2 micro instances that evaluates the complex interactions between cost, performance, idleness and CPU throttling. Next, we define adaptive algorithms to manage CPU consumption by learning the workload characteristics at runtime and by injecting idleness to diminish host-level throttling. Experimental results show that a gradient-hill strategy leads to favorable results. For CPU bound workloads, we observe that a significant portion of jobs (up to 65%) can have end-to-end times that are even four times shorter than those of the more expensive m1.small class. Our algorithms drastically reduce the long tails of job execution times on the micro instances, resulting to favorable comparisons against even small instances. TABLE OF CONTENTS Acknowledgments ii
Determinación de la calidad ambiental de las aguas de los ríos de El Salvador, utilizando invertebrados acuáticos: índice biológico a nivel de familias de invertebrados acuáticos en El Salvador (IBF-SV-2010)

La medicion de la calidad ambiental del agua de los rios se ha realizado tradicionalmente a traves de parametros fisico-quimicos y microbiologicos, los cuales son muy precisos, aunque tambien onerosos. Aqui, los referidos parametros actuan como una “fotografia” del momento en el que se toma la muestra, entregando caracteristicas inmediatas sobre las aguas de los rios; sin embargo, no permiten una vision de las variaciones de las caracteristicas en el tiempo. Una alternativa complementaria a este metodo tradicional, es por medio de indicadores biologicos (tambien llamados bioindicadores), el cual es relativamente poco costoso. Este metodo biologico presenta amplias ventajas y nos permite una vision mas integral y ademas retrospectiva de las cualidades del medio en el cual se desarrollan los organismos acuaticos.
Edge influence on vegetation at natural and anthropogenic edges of boreal forests in Canada and Fennoscandia

Although anthropogenic edges are an important consequence of timber harvesting, edges due to natural disturbances or landscape heterogeneity are also common. Forest edges have been well studied in temperate and tropical forests, but less so in less productive, disturbance‐adapted boreal forests. We synthesized data on forest vegetation at edges of boreal forests and compared edge influence among edge types (fire, cut, lake/wetland; old vs. young), forest types (broadleaf vs. coniferous) and geographic regions. Our objectives were to quantify vegetation responses at edges of all types and to compare the strength and extent of edge influence among different types of edges and forests. Research was conducted using the same general sampling design in Alberta, Ontario and Quebec in Canada, and in Sweden and Finland. We conducted a meta‐analysis for a variety of response variables including forest structure, deadwood abundance, regeneration, understorey abundance and diversity, and non‐vascular plant cover. We also determined the magnitude and distance of edge influence (DEI) using randomization tests. Some edge responses (lower tree basal area, tree canopy and bryophyte cover; more logs; higher regeneration) were significant overall across studies. Edge influence on ground vegetation in boreal forests was generally weak, not very extensive (DEI usually < 20 m) and decreased with time. We found more extensive edge influence at natural edges, at younger edges and in broadleaf forests. The comparison among regions revealed weaker edge influence in Fennoscandian forests. Synthesis. Edges created by forest harvesting do not appear to have as strong, extensive or persistent influence on vegetation in boreal as in tropical or temperate forested ecosystems. We attribute this apparent resistance to shorter canopy heights, inherent heterogeneity in boreal forests and their adaptation to frequent natural disturbance. Nevertheless, notable differences between forest structure responses to natural (fire) and anthropogenic (cut) edges raise concerns about biodiversity implications of extensive creation of anthropogenic edges. By highlighting universal responses to edge influence in boreal forests that are significant irrespective of edge or forest type, and those which vary by edge type, we provide a context for the conservation of boreal forests.
Dripping Modes of Newtonian Liquids: The Effect of Nozzle Inclination

: The dripping modes for a Newtonian liquid of viscosity µ emanating from an inclined nozzle at flow rate Q is investigated experimentally. As the liquid flow rate Q increases, starting with period-1 with satellite drops, the system transitions to period-1 dripping without satellite, then to limit cycle before showing chaotic responses. Phase diagrams shows the changes in the transitions between the different dripping modes for different nozzle inclination angle θ is constructed in the dimensionless (Q, µ) space.
The role of symbiotic arbuscular mycorrhizal fungi (Glomeromycota) in roots of the host plant Deschampsia flexuosa in vegetation succession of inland sand dunes in Finnish Lapland

Most of all land plant species and families are mycorrhizal, and the majority of them house the symbiont arbuscular mycorrhizal (AM) fungi in their roots. The attachment between the host plant and the mycorrhizal fungus is called a mutualistic symbiosis. The heterotrophic AM fungi rely on organic carbon provided by their plant hosts and in return the fungi can improve their host plants nutrients acquisition, provide protection from pathogens and herbivores, and tolerance of water deficit. By affecting the plant's resource allocation and growth, AM fungi may affect the interactions between plants and thus alter the composition of plant and soil microbial communities. I studied the role of AM fungi in vegetation succession of inland sand dunes in Finnish Lapland. I assessed the mycorrhizal status of a host plant as percent root length colonized (%). The study plant, Deschampsia flexuosa, grew both in the deflation basins (the beginning of succession) and in the vegetated dunes (the climax) in the study area. Mycorrhizal colonization is generally common in old and stabilized ecosystems and absent or low in early successional phases of ecosystems, or in ecosystem suffering from severe disturbances. Colonization tends to be high when the amount of inorganic nutrients in soil is low and competition for sparse resources is intense. In this study I found that the colonization of roots was greater in the disturbed deflation basins than in the stabilized vegetated dunes, which was contrary to what was expected. For one reason or the other it seems that the host plants in the deflation basins are more dependent on AM fungi but to find out for what, we need to study further.

Fracture Behaviour of ODS 410L Stainless Steel using Small Punch Test

The fracture behavior of oxide dispersion strengthened (ODS) 410L stainless steels was investigated by means of small punch testing and scanning electron microscopy. The results showed that there are noticeable strengthening effects by the addition of 0.9 μm yttria into 410L steel. Small punch testing was also conducted on a specimen of ODS 410L steel with 50 nm yttria irradiated by helium ion beam with a dose of 2 × 10 16 ion.cm–2. The small punch test is an effective method to reveal the irradiation effects in the materials.
On the possibilities of x-ray phase contrast microimaging by coherent high-energy synchrotron radiation

Coherent properties of the x-ray beam delivered at the ESRF allow the observation of very weak perturbations of the wave front, resulting in the phase contrast. A straightforward experimental setup for phase contrast imaging is proposed and used to record holographic images from organic samples of 10-100 pm at energy lo-50 keV with the contrast up to 50%-100%. The theory of phase contrast imaging is considered and some theoretical estimations are made to reveal the performance of the proposed technique in terms of resolution, sensitivity, geometrical requirements, and ehergy range applicability. It is found that for carbon-based fibers a detectable size with 2% contrast is 0.1 ,um for 10 keV and - 1 pm for 100 keV, It is demonstrated that the fine interference structure of the image is very sensitive to the shape, density variation, and internal structure of the sample. Some prospects for the practical use and future development of the new coherent techniques such as phase contrast microscopy, microtomography, holography, and interferometry at high energies are also discussed. 0 I995 American Institute of Physics.
Recognition of Self Among Persons With Dementia

The physical environment can promote the functional ability of persons with dementia. Many care facilities use environmental signage (e.g., names on doors) to facilitate adaptive behavior (e.g., room finding). However, the effects of such signage on residents’functioning are not well understood. In three experiments, we investigated if persons with moderate to severe dementia had the required skills necessary to benefit from signage. Compared to a control condition (recognition of fellow residents’ photographs), a high percentage of participants could identify written names and photographs of themselves (Experiment 1). Moreover, name and photographic labels helped participants identify belongings (Experiment 2). Training improved some participants’ recognition of their own photographs but not of their fellow residents’ photographs (Experiment 3). These findings are consistent with research on self-reference and age-related changes in face recognition and reading, and they suggest that many persons with dementia may have the requisite abilities to benefit from prosthetic signage.
Characterization of Metal-binding P-loop GTPases: E. coli YeiR and M. thermoacetica AcsF

Organisms express metal-binding proteins in order to deal with essential metal ions that can be potentially toxic. A common trend of bacterial metal homeostasis pathways is the presence of a GTPase, and several of these proteins are members of the G3E family of P-loop GTPases. In this work we focused on E. coli YeiR, member of the under-characterized COG0523 subfamily, and on M. thermoacetica AcsF. The in vitro metal-binding properties of isolated YeiR are presented. The protein binds Ni and Zn with low micromolar affinity, and oligomerizes in the presence of metal. The GTPase activity of YeiR is similar to that measured for other members of the group and is enhanced by Zn. In the case of AcsF, it was not possible to establish concluding evidence that the protein binds metal. This study helps shed light upon members of the undercharacterized subfamily of G3E P-loop GTPases.
Tsunami response in semienclosed tidal basins using an aggregated model

An aggregated model to evaluate tsunami response in semienclosed water bodies is presented in this work. The model is based on one-dimensional shallow water equations and can include long-wave external forcing such as a tsunami. It has been successfully validated against experimental data from a physical model, and its predictions for a case study have been compared with results from the Cornell multigrid coupled tsunami (COMCOT) model. The model can be used as a predictive tool because a calibration using a theoretical value for expansion and contraction losses has been performed and differences with the typical calibration are less than 10%, which is considered acceptable. This allows using the model in the absence of measured data, which is very difficult to obtain in case of a tsunami event. A case study for the Gulf of Cadiz (Spain) has been simulated with the COMCOT model. The aggregated model predicted the response for a harbor more accurately than for estuarine systems with tidal flats. Nevertheless, the aggregated model has been demonstrated as a useful general tool to predict the response of semienclosed tidal basins to a tsunami event, and hybrid models coupling advanced models to simulate ocean tsunami propagation with the model presented here would be useful in developing coastal warning alert systems.
Analysis of Prolactin Gene Exon 4 Diversity in Peking, White Mojosari, and Peking White Mojosari Crossbreed

Genetic marker linked to loci reproductive traits could be used to increase an effectiveness of improvement in animal breeding. Association between DNA polymorphism and a trait could be considered as candidate genetic marker for marker assisted selection (MAS) programs. Prolactin (PRL) is one of polypeptide hormones secreted by anterior pituitary gland in vertebrates. PRL plays an important role in onset of poultry incubation and brooding behavior. The aim of this study was to investigate the diversity of prolactin gene and to characterize the type of mutation in partial intron 3, intron 4 and exon 4 of duck prolactin gene. Blood extraction was collected from 168 ducks consisted of 19 Peking, 36 Mojosari, and 113 Peking White Mojosari (Peking Mojosari putih) ducks. Polymerase chain reaction of fragment prolactin gene exon 4 and partial intron 3 and 4 have been successfully amplified with length of base pair were 496 bp. A total of 30 µL PCR product from each sample were sequenced for forward sequence using BIOTRACE 3730 by First Base Company, Malaysia. Alignment analysis found six SNP consisted of g.3941T>G, g.3975C>A, g.4110T>C, INDEL 3724A, INDEL 34031, and INDEL 3939A. Analysis of SNP frequency result indicated mutation of INDEL 3724A, g.3941T>G, g.3975C>A, INDEL 4031A and g.4110T>A in duck sample were polymorphic and INDEL 3939A were monomorphic.
