description: Weyl semimetals are phases of matter with excitations effectively described by massless Dirac fermions. Their critical nature makes unclear the persistence of such phase in presence of disorder. We present a theorem ensuring the stability of the semimetallic phase in presence of weak quasiperiodic disorder. The proof relies on the subtle interplay of the relativistic Quantum Field Theory description combined with number theoretical properties used in KAM theory.

description: A detailed description of the tunneling processes within Aharonov-Bohm (AB) rings containing two-dimensional quantum dots is presented. We show that the electronic propagation through the interferometer is controlled by the spectral properties of the embedded dots and by their coupling with the ring. The transmittance of the interferometer is computed by the Landauer-Büttiker formula. Numerical results are presented for an AB interferometer containing two coupled dots. The charging diagrams for a double-dot interferometer and the Aharonov Bohm oscillations are obtained, in agreement with the recent experimental results of Holleitner {\it et al}. [Phys. Rev. Lett. {\bf 87}, 256802 (2001)] We identify conditions in which the system shows Fano line shapes. The direction of the asymetric tail depends on the capacitive coupling and on the magnetic field. We discuss our results in connection with the experiments of Kobayashi {\it et al} [Phys. Rev. Lett. {\bf 88}, 256806 (2002)] in the case of a single dot.

description: Observations are studied in toy-models constituting exact cosmological solutions to the Einstein equation which are statistically homogeneous but locally inhomogeneous, without an a priori introduced FLRW background and with "structures" evolving fairly slowly. The mean redshift-distance relation and redshift drift along 500 light rays in each of two models are compared to relations based on spatial averages. The relations based on spatial averages give a good reproduction of the mean redshift-distance relation, although most convincingly in the model where the kinematical backreaction is subpercent. In both models, the mean redshift drift clearly differs from the drift of the mean redshift. This indicates that redshift drift could be an important tool for testing the backreaction conjecture as redshift drift appears to distinguish between local and global effects. The method presented for computing the redshift drift is straightforward to generalize and can thus be utilized to fairly easily compute this quantity in a general spacetime.

subject: FOS: Physical sciences

description: Three most long and dense VLBI nutation series obtained at the Goddard Space Flight Center, Institute of Applied Astronomy, and U.S. Naval Observatory were used for investigation of the Free Core Nutation (FCN) contribution to the celestial pole offset. Some recent studies have showed that the FCN period or/and phase does not remain constant, but varies in a rather wide range of about 410--490 days (for equivalent period). To implement this result in the practice, a new FCN model with variable amplitude and period (phase) is developed. Comparison of this model with observations shows better agreement than existing one. After correction of the differences between observed VLBI nutation series and the IAU2000A model, they decreased to a level about 100 microarcseconds.

description: O uso da expressão território ganha espaço no Brasil com a nova orientação política federal, a partir de 2003. Nesse contexto, as ações estratégicas do Estado para o desenvolvimento tendem a não mais considerar o município isoladamente. Como estímulo, tem-se a liberação de recursos vinculados ao território pelas instituições públicas de crédito e financiamento. No entanto, a permanência de práticas como a liberação de recursos mediante o grau de articulação política dos municípios causa desconfiança e desmotivação quanto à manutenção do território. Surgem grupos de municípios que se articulam entre si de forma independente. Neste artigo analisam-se esses fatos apresentados como reveses à questão territorial. A partir das experiências na região de Irecê (Bahia) observa-se que ainda existem ações objetivando a melhor compreensão e funcionamento do território, como por exemplo, a capacitação dos representantes municipais e a imparcialidade das instituições internas com poder de decisão. Percebe-se que, executando-se tais ações, tornam-se possíveis a viabilidade administrativa e a manutenção do território.

Blue Stragglers in Galactic Open Clusters and the Integrated Spectral Energy Distributions

description: Synthetic integrated spectral properties of the old Galactic open clusters are studies in this work, where twenty-seven Galactic open clusters of ages >= 1Gyr are selected as the working sample. Based on the photometric observations of these open clusters, synthetic integrated spectrum has been made for the stellar population of each cluster. The effects of blue straggler stars (BSSs) on the conventional simple stellar population (SSP) model are analyzed on an individual cluster base. It is shown that the BSSs, whose holding positions in the color-magnitude diagrams (CMDs) cannot be predicted by the current single-star evolution theory, present significant modifications to the integrated properties of theoretical SSP model. The synthesized integrated spectral energy distributions (ISEDs) of our sample clusters are dramatically different from the SSPs based on isochrone only. The BSSs corrected ISEDs of stellar populations show systematic enhancements towards shorter wavelength in the spectra. When measured with wide-band colors in unresolvable conditions, the age of a stellar population can be seriously under-estimated by the conventional SSP model. Therefore, considering the common existence of BSS component in real stellar populations, a considerable amount of alternations on the conventional ISEDs should be expected when applying the technique of evolutionary population synthesis (EPS) to more complicated stellar systems.

Ecological genetics and effects of inbreeding and white pine blister rust on genetic structure of whitebark pine (Pinus albicaulis Engelm.)
Creators: name: Bower, Andrew David
Publisher: name: University of British Columbia
Year: 2010

description: In this thesis I investigate the ecological genetics of whitebark pine (Pinus albicaulis Engelm.), a five-needle pine found near treeline in western North America. Throughout its range whitebark pine is experiencing declines due to the introduced disease white pine blister rust and successional replacement due to fire suppression. Conservation and restoration efforts are needed to reverse this decline; however, little is known about the genetics of whitebark pine as related to quantitative traits. A common garden experiment was used to assess rangewide genetic variation and geographic differentiation of quantitative traits. Significant variation among provenances was detected for all traits except spring cold injury. Geographic differentiation was weak to moderate for growth and biomass traits, but was strong for fall cold injury and date of needle flush. Both of these variables were significantly associated with mean temperature of the coldest month at of source location. These results were used to determine guidelines for seed movement in whitebark pine management and restoration. Isozyme analysis of seed tissues was used to determine the mating system and presence and strength of inbreeding depression in quantitative traits. Regional estimates of outcrossing rate (tm) ranged from 0.73 to 0.93, with a mean of 0.86. Family mean tm values were skewed towards outcrossing; however, some individuals experienced substantial inbreeding. Biomass in the southern B.C. region was the only trait and geographic origin with significant inbreeding depression, and is predicted to be reduced by 19.6% in this region. Isozyme analysis of bud tissue was used to determine genetic diversity (Ho and He) and fixation index (Fis) for three age cohorts, from 14 sites. Significant evidence of inbreeding (Fis>0) was found in all age cohorts. When sites were stratified by level of blister rust infection, differences in Fis and Ho among cohorts were only significant when level of infection was low. A significant negative association with level of rust infection was found for Ho only in the mature cohort. This suggests that when differential selection due to rust is weak, more heterozygous individuals are favoured. However, more homozygous individuals appear to have higher fitness when rust infection levels are high.

description: Cardiac contraction is the result of integrated cellular, tissue and organ function. Biophysical in silico cardiac models offer a systematic approach for studying these multi-scale interactions. The computational cost of such models is high, due to their multi-parametric and nonlinear nature. This has so far made it difficult to perform model fitting and prevented global sensitivity analysis (GSA) studies. We propose a machine learning approach based on Gaussian process emulation of model simulations using probabilistic surrogate models, which enables model parameter inference via a Bayesian history matching (HM) technique and GSA on whole-organ mechanics. This framework is applied to model healthy and aortic-banded hypertensive rats, a commonly used animal model of heart failure disease. The obtained probabilistic surrogate models accurately predicted the left ventricular pump function (R2 = 0.92 for ejection fraction). The HM technique allowed us to fit both the control and diseased virtual bi-ventricular rat heart models to magnetic resonance imaging and literature data, with model outputs from the constrained parameter space falling within 2 SD of the respective experimental values. The GSA identified Troponin C and cross-bridge kinetics as key parameters in determining both systolic and diastolic ventricular function.This article is part of the theme issue ‘Uncertainty quantification in cardiac and cardiovascular modelling and simulation’.
On the Robustness of Deep Learning-predicted Contention Models for Network Calculus

description: The network calculus (NC) analysis takes a simple model consisting of a network of schedulers and data flows crossing them. A number of analysis "building blocks" can then be applied to capture the model without imposing pessimistic assumptions like self-contention on tandems of servers. Yet, adding pessimism cannot always be avoided. To compute the best bound on a single flow's end-to-end delay thus boils down to finding the least pessimistic contention models for all tandems of schedulers in the network - and an exhaustive search can easily become a very resource intensive task. The literature proposes a promising solution to this dilemma: a heuristic making use of machine learning (ML) predictions inside the NC analysis.
 While results of this work were promising in terms of delay bound quality and computational effort, there is little to no insight on when a prediction is made or if the trained algorithm can achieve similarly striking results in networks vastly differing from its training data. In this paper, we address these pending questions. We evaluate the influence of the training data and its features on accuracy, impact and scalability. Additionally, we contribute an extension of the method by predicting the best $n$ contention model alternatives in order to achieve increased robustness for its application outside the training data. Our numerical evaluation shows that good accuracy can still be achieved on large networks although we restrict the training to networks that are two orders of magnitude smaller.

description: The goal of the research is to estimate the supply and demand of grain storage for the state of Mato Grosso. This is the first research to employ GPS coordinates to map storage in Mato Grosso. The state has 2,143 registered warehouses. The analysis uses commercial warehouses with capacity greater than 50,000 metric tons as the focus of study. There is an under capacity of 34% compared to production and the situation is aggravated by the rapidly increasing production of second crop maize (safrinha). The worst situation occurs in Sorriso with a maximum deficit of 6,904,730 tons of storage when factoring in a full maize second crop. There is clear evidence of a shortage of storage, particularly private and cooperative, as grain production rises in the state

description: We introduce the concept of Magic Subspaces for the control of dissipative N- level quantum systems whose dynamics are governed by Lindblad equation. For a given purity, these subspaces can be defined as the set of density matrices for which the rate of purity change is maximum or minimum. Adding fictitious control fields to the system so that two density operators with the same purity can be connected in a very short time, we show that magic subspaces allow to derive a purity speed limit, which only depends on the relaxation rates. We emphasize the superiority of this limit with respect to established bounds and its tightness in the case of a two-level dissipative quantum system. The link between the speed limit and the corresponding time-optimal solution is discussed in the framework of this study. Explicit examples are described for two- and three- level quantum systems.

In particular, we show that positive, entire minimal graphs on manifolds with non-negative Ricci curvature are constant, and that complete, parabolic manifolds with Ricci curvature bounded from below have the half-space property. We avoid the need of sectional curvature bounds on $M$ by exploiting a form of the Ahlfors-Khas'minskii duality in nonlinear potential theory.

Utilizando-se medidas de localização e especialização, como o quociente locacional, o coeficiente de especialização e o coeficiente de reestruturação, procurou-se analisar os principais setores da economia, visando determinar aqueles que seriam os mais dinâmicos e ou aquele(s) estado(s) que apresentaram alguma reestruturação setorial. Por meio dos coeficientes de localização e especialização, nota-se que a estrutura produtiva dos estados nordestinos é bastante homogênea, fato que é confirmado pela análise do quociente locacional, que mostrou uma concentração relativa dos setores 1 e 7 (Agrícola e Outras atividades), juntamente com o coeficiente de especialização, que apresentou uma baixa variação entre os estados, com a exceção da Paraíba, que apresentou uma expressiva variação interperíodos. A Bahia, com exceção do setor 1, possui os setores mais dinâmicos da região (2, 3, 4, 5, 6 e 7), o segundo maior coeficiente de especialização e o maior coeficiente de reestruturação, o que indica alguma modificação na composição setorial deste estado

description: The thesis reviewed and assessed studies on forest trees inside the Chernobyl Exclusion Zone. Eleven studies discussing radiation impact on various levels were evaluated and analysed. Consequences were found in terms of population, cellular and subcellular, genetic and intergenerational impacts. The noticeable recovery of biota in the vicinity of the ChNPP raised the issue of redevelopment and resettlement in areas affected by the fallout. A contrasting opinion offered by scientists stated that visible signs of repair by the biota were not enough indications of recuperation. Forest trees surrounding the V.I. Lenin reactor as a component of the environment that survived the worst of the fallout is a good starting point for discussion but it is not taken as a representative of the whole ecosystem. Results of the study signified that forest trees which did not absorbed the lethal threshold dose employed different mechanisms including morphological and physiological means to limit the damage. The low intensity of mutation found in specimens exposed to either high acute or chronic or both types of radiation suggested that defense mechanisms that do not excessively rearrange DNA were preferred over other repair systems. The strong relationship between mutability and sterility is interpreted as protecting strongly damaged genetic material from being passed on to future generations. Assessment of other environmental components is further recommended.
Exploratory research on branding Canadian wood products in China
Creators: name: Yan, Xiaoqian
Publisher: name: University of British Columbia
Year: 2010

description: This research focuses on understanding China’s market background, the changing Chinese consumer, and exploring the role of branding information on certain members of the Chinese wood products industry. This information could help Canadian wood products firms increase exports to the Chinese market by the judicious use of branding strategies. The specific objectives of this exploratory research are to: identify the branding awareness of some Chinese wood products users; determine which branding variables are important to these wood products users in terms of purchase decisions; and explore the sources of information on brands for these wood products users. A written survey was developed to collect primary data from wood products users in China. A total of 85 respondents (~50% of all Chinese attendees) attending the China Wood Markets Export & Import Conference held in Dalian city, Liaoning province from October 26th to 29th, 2004 completed the survey. Results of the survey indicate that performance/quality was the most important core value of brands wood for products. Competitive pricing, after-sales service and effective promotion, were viewed as three other important factors in terms of the relative importance in brands for wood products. Therefore, these values should form the core of the brand developed by Canadian wood products firms to improve opportunities in China’s competitive market. A successful brand would ensure consistent quality recognition and help a firm survive and grow in increasingly global competitive markets. Canadian wood products firms should be aware of the importance of branding their own products in China and develop, maintain and enhance their brands. Further research in China could determine specific aspects of a branding strategy. Firms should have a long-term commitment to the Chinese market since Chinese wood products users consider after-sales service as one of the top benefits for wood products brands. Branding could help ensure high enough volumes to provide some economies of scale to reduce costs resulting from providing such services. Chinese wood products users prefer to obtain brand information through TV and Internet promotions and these media should be effective conduits for Canadian wood companies wanting to brand in China.

description: Body size is a key functional trait that is predicted to decline under warming. Warming is known to cause size declines via phenotypic plasticity, but evolutionary responses of body size to warming are poorly understood. To test for warming-induced evolutionary responses of body size and growth rates, we used populations of mosquitofish (Gambusia affinis) recently established (less than 100 years) from a common source across a strong thermal gradient (19–33°C) created by geothermal springs. Each spring is remarkably stable in temperature and is virtually closed to gene flow from other thermal environments. Field surveys show that with increasing site temperature, body size distributions become smaller and the reproductive advantage of larger body size decreases. After common rearing to reveal recently evolved trait differences, warmer-source populations expressed slowed juvenile growth rates and increased reproductive effort at small sizes. These results are consistent with an adaptive basis of the plastic temperature-size rule, and they suggest that temperature itself can drive the evolution of countergradient variation in growth rates. The rapid evolution of reduced juvenile growth rates, and greater reproduction at a small size, should contribute to substantial body downsizing in populations, with implications for population dynamics and for ecosystems in a warming world.

description: The geometric picture of neutrino oscillations offers a unique way to study the quantum mechanics of this phenomenon. In this picture, the propagation of a neutrino beam is described by a density matrix evolving in a state space with non-trivial geometry. We derive explicit expressions of the mixed state geometric phase which arise during such an evolution for both two and three flavor neutrino oscillations. We show that, in the case of two flavor neutrino oscillations, the geometric phase is independent of the Majorana phase and it can be used as a measure of coherence of the neutrino beam.

description: Este artigo teve como objetivo analisar a visão neoclássica do desenvolvimento econômico a partir da modernização agrícola, particularmente, para os países em desenvolvimento. Para isso, teve-se como fonte teórico-empírica de análise as abordagens de Schultz e Paiva para o crescimento da agricultura. Constatou-se que, mesmo após anos de apresentação e discussão dos modelos apresentados por esses dois autores, os mesmos permanecem carentes de uma revisão crítica, tendo em vista que suas análises não perderam espaço, tanto no campo de política agrícola e econômica, quanto na realidade dos países em desenvolvimento.Assim, fez-se uma leitura dos escritos desses autores, além de seus críticos. Segundo Schultz, pela análise dos insumos de alto rendimento na agricultura poder-se-ia promover o crescimento de um país. Contudo, essa visão admitia o princípio da racionalidade plena para os agricultores e, logo, desconsiderava os legados da antropologia para a tomada de decisão desses agentes. Paiva apresentou a idéia de manter um setor agrícola moderno e um tradicional, pois o setor não-rural seria incapaz de absorver toda a produção, o que empobreceria o meio rural. Esta interpretação desconsiderou o equilíbrio geral da economia e a possibilidade de absorção da produção pelo mercado externo. Naprática, variáveis exógenas, como a intervenção dos governos no mercado e os conseqüentes efeitos sobre o comércio de bens agrícolas e sobre a renda daqueles que vivem no meio rural, não permitiram averiguar sobre a validade ou não das interpretações desses autores, inspiradas na hipótese neoclássica de mercados perfeitamente competitivos.

description: We prove global well-posedness of the initial value problem for a class of variational quasilinear wave equations, in one spatial dimension, with initial data that is not-necessarily small. Key to our argument is a form of quasilinear null condition (a "nilpotent structure") that persists for our class of equations even in the large data setting. This in particular allows us to prove global well-posedness for $C^2$ initial data of moderate decrease, provided the data is sufficiently close to that which generates a simple traveling wave.
 We take here a geometric approach inspired by works in mathematical relativity and recent works on shock formation for fluid systems. First we recast the equations of motion in terms of a dynamical double-null coordinate system; we show that this formulation semilinearizes our system and decouples the wave variables from the null structure equations. After solving for the wave variables in the double-null coordinate system, we next analyze the null structure equations, using the wave variables as input, to show that the dynamical coordinates are $C^1$ regular and covers the entire space-time.

description: Cardiac contraction is the result of integrated cellular, tissue and organ function. Biophysical in silico cardiac models offer a systematic approach for studying these multi-scale interactions. The computational cost of such models is high, due to their multi-parametric and nonlinear nature. This has so far made it difficult to perform model fitting and prevented global sensitivity analysis (GSA) studies. We propose a machine learning approach based on Gaussian process emulation of model simulations using probabilistic surrogate models, which enables model parameter inference via a Bayesian history matching (HM) technique and GSA on whole-organ mechanics. This framework is applied to model healthy and aortic-banded hypertensive rats, a commonly used animal model of heart failure disease. The obtained probabilistic surrogate models accurately predicted the left ventricular pump function (R2 = 0.92 for ejection fraction). The HM technique allowed us to fit both the control and diseased virtual bi-ventricular rat heart models to magnetic resonance imaging and literature data, with model outputs from the constrained parameter space falling within 2 SD of the respective experimental values. The GSA identified Troponin C and cross-bridge kinetics as key parameters in determining both systolic and diastolic ventricular function.This article is part of the theme issue ‘Uncertainty quantification in cardiac and cardiovascular modelling and simulation’.

description: Cybaeodes Simon Cybeodes Simon, 1878: 205 (type species by monotypy Cybeodes testaceus Simon). Cybaeodes: Simon, 1893: 387 (corrected spelling, original name based on the generic name Cybaeus, which was also misspelled as Cybeus by Simon, 1878: 206). Cerrutia Roewer, 1960: 88 (type species by original designation Cerrutia molara Roewer). NEW SYNONYMY. DIAGNOSIS: Cybaeodes can easily be recognized by the combined presence of gnaphosid-like anterior lateral spinnerets in males (but not females) and two ventral rows of modified setae on the anterior legs of both sexes. The extremely small eyes (see Roewer, 1960: Fig. la) seem also to be diagnostic (both of the cavernicolous species C. molara and the other, presumably epigean species), and we would not be surprised to find that blind, cavemicolous members of Cybaeodes occur in Mediterranean caves. DESCRIPTION: To the detailed descriptions provided by Roewer (1960) and Di Franco (1989), we can add that the trichobothrial bases bear several chevron-shaped ridges (Fig. 9), that the tarsal organ is elongate, with a round opening and elevated receptors (Fig. 10), and that the male palpal tibia bears a small prolateral lobe (as in Liocranum and Hesperocranum). SYNONYMY: Roewer's redescription of the genus can probably be ascribed to Simon's lack of Cybaeodes males and his association of the genus more closely with gnaphosids than with other liocranids.

title: Verkehrsplanung im Spannungsfeld zwischen Erreichbarkeit und Nachhaltigkeit - Leistungsfähigkeit der Verkehrswertanalyse bei strategischen Entscheidungen im Verkehr am Beispiel Südtirols
Creators: name: Demanega, Michael
Publisher: name: TU Wien

Subjects: subject: Verkehrswertanalyse

description: Im Mittelpunkt der Diplomarbeit stehen die Konzepte Nachhaltigkeit und Erreichbarkeit, die in der verkehrspolitischen Debatte heute von zentraler Bedeutung sind ohne dass in der verkehrsplanerischen Praxis Methoden und Modelle zur Anwendung kommen, die die dynamischen und vielfältigen Auswirkungen von Infrastrukturvorhaben im Vorfeld abschätzen. Im Rahmen dieser Diplomarbeit wird folglich versucht, unter Verwendung der Verkehrswertanalyse als ein Instrument zur Verkehrsmodellierung, verschiedene verkehrsplanerische Szenarien quantitativ und qualitativ zu bewerten. Inhaltlich bezieht sich die Arbeit auf Südtirol als ein ländliches Gebiet. Damit soll dem Umstand Rechnung getragen werden, dass sich zahlreiche verkehrswissenschaftliche Untersuchungen derzeit auf den urbanen Raum beziehen und der ländliche Raum vielfach vernachlässigt wird, obwohl nach wie vor der Hauptteil der Bevölkerung zahlreicher europäischer Länder am Land lebt und der ländliche Raum ganz besondere Herausforderungen und Erfordernisse hat, die bewältigt werden wollen. Analysiert werden insbesondere die wechselhaften Beziehungen zwischen Verkehrsinfrastruktur und ländlicher Entwicklung, sodass es möglich wird, quantitative und qualitative Aussagen zu verschiedenen verkehrsplanerischen Szenarien zu tätigen, die als strategische Entscheidungsgrundlage dienen können.
description: The focus of this master thesis is on the concepts of sustainability and accessibility, which are given nowadays central importance in the transport policy debate. Attention should be paid on the fact that methods and models to previously evaluate the dynamic and diverse effects of infrastructure projects in the run-up, are not been taken into consideration. The scope of this master thesis is consequently to evaluate quantitatively and qualitatively various traffic-planning scenarios, using traffic value analysis as a tool for traffic modelling. In terms of content, this master thesis is referring to South Tyrol as a rural area. This takes account of the fact that numerous studies on transport sciences are currently referring to urban areas. The rural area is often neglected, although the bulk of the population of many European countries still lives in rural areas. Rural areas face very special challenges and requirements that need to be solved. In particular, the interrelation between transport infrastructure and rural development is analysed, in order to get reliable quantitative and qualitative values and statements on various traffic-planning scenarios, which can serve as a strategic decision-making basis.

description: O Brasil é reconhecidamente um dos maiores fornecedores mundiais de carnes, responsável por parte do abastecimento de diversos países. Nesse início de 2006 o MAPA relaciona 270 matadouros de bovinos e 123 de suínos distribuídos em todo o território nacional como SIF. De acordo com os dados do IBGE, os abates de bovinos totalizam cerca de 20,7 milhões de cabeças em 2005 e os de suínos, 21,8 cabeças, volumes que vêm aumentando ano após ano. O aproveitamento do sangue, assim como de outros subprodutos do abate nem sempre representa alguma forma de lucratividade para a indústria abatedora, embora o conjunto dos subprodutos garanta parte da rentabilidade do setor. O presente estudo aponta o direcionamento atual do sangue resultante dos abates de bovinos e suínos no Brasil. Por meio da quantificação do volume de abate e conseqüentemente, de sangue produzido, tem-se o conhecimento do potencial fornecedor desse subproduto, que de modo geral é visto pelos frigoríficos como um resíduo problemático de seu processo de transformação. Além disso, por intermédio de um mapeamento dessas unidades nas principais praças de abate, é possível detectar regiões com forte representatividade para produção de sangue e também por isso, consideradas promissoras ao fornecimento desse produto. Constatado, portanto, como forma de melhorar a lucratividade das unidades de processamento ou mesmo como maneira de solucionar o problema do resíduo, o aproveitamento do sangue pode e deve ser tratado estrategicamente por frigoríficos de bovinos e suínos, contribuindo para amenizar alguns dos principais riscos associados à atividade, dentre eles o ambiental. Em última análise, tem-se ainda a transparência do potencial a ser explorado pela indústria que usa o sangue como matéria-prima, o que além de representar uma oportunidade de investimento, poderia contribuir para amenizar problemas de ordem social.
