description: As tecnologias de Agricultura de Precisão (AP) já são adotadas nas lavouras do Brasil, com técnicas cada vez mais produtivas, indispensáveis para garantir a liderança do País na produção agrícola. No entanto, ainda não existem estudos sobre a intensidade do uso das tecnologias de AP no País e dos condicionantes de sua adoção. O desafio central deste trabalho foi, então, investigar o processo de adoção e uso das tecnologias de AP alcançado pela indústria sucroalcooleira no estado de São Paulo. Para tanto, foram utilizados dados primários, a partir de encaminhamento de questionário a todas as empresas do setor sucroalcooleiro paulista, com o objetivo de conhecer não só o grau de adoção e uso das tecnologias de AP, mas também de verificar a influência das variáveis estudadas na probabilidade de adoção dessas tecnologias. As conclusões deste trabalho sugerem não apenas que o percentual de adoção das tecnologias de AP é elevado na indústria sucroalcooleira paulista, mas também que a probabilidade de adotar tais tecnologias é maior em ordem decrescente de importância, em usinas/destilarias de capital nacional, que fazem parte de um grupo empresarial, de orientação exportadora, de gestão profissional, e que utilizam maior percentual de recursos próprios para investimentos na empresa......Technologies of Precision Agriculture (PA) are already a reality in crops throughout Brazil, using more and more productive techniques, crucial to ensure the country as the world leader in agriculture. However, studies on the intensity of the use of PA technologies in Brazil and the determiners of their adoption do not exist yet. The main focus of this study was, therefore, to investigate the adoption process and the use of PA technologies in the sugarcane industry in São Paulo state. For that purpose, it used primary data based upon a questionnaire submitted to all enterprises of the sugarcane sector in the state, aiming to figure out not only the adoption level and use of PA technologies in the sugarcane industry, but also to verify the influence of the variables studied on the probability for the adoption of the PA technologies. The conclusions of this study suggest that the percentage for the PA adoption is high in the sugarcane industry of São Paulo and also that the probability to adopt PA technologies is higher in decrescent order of importance in mills/distilleries of national capital, which are part of an export-driven group, of professional management and that use higher percentage of their own resources.

description: Com o passar dos anos, o Pronaf (Programa Nacional de Fortalecimento da Agricultura Familiar) foi se estruturando e ampliou significativamente seu campo de atuação. Além do aumento dos recursos, contratos e número de agricultores beneficiados, uma importante inovação desse programa foi a inclusão de novas linhas de financiamento, seja através da inserção de segmentos até então renegados pelas políticas agrícolas ou pelo reconhecimento e legitimação das atividades diferenciadas no meio rural, como é o caso da agroindustrialização em escala familiar. O objetivo central desse artigo é analisar a política de crédito rural direcionada às agroindústrias familiares (Pronaf-Agroindústria), trazendo em evidência a constituição, elaboração, implementação e os resultados alcançados por essa linha de financiamento. Além disso, é discutido o processo de reformulação das condições de acesso ao crédito ao longo dos últimos anos, problematizando o novo portfólio que se alcançou com a efetivação do Programa Mais Alimentos. Os resultados deste trabalho destacam a flexibilização das condições financeiras do Pronaf- Agroindústria (redução da taxa de juros, aumento do teto financiado e alastramento no público-alvo), alterando significativamente o foco de atuação da política (que deixa de ser exclusivamente as pequenas agroindústrias familiares e passa a englobar, também, as grandes cooperativas de leite)......During the years, since its implementation, Pronaf has become more structured and has significantly increased its action field. Alongside the increase of resources, contracts, and number of benefited agriculturists, an important innovation of this program was the inclusion of new lines of funding, either through inserting segments until then, excluded from the agricultural policies, or including, recognizing, and legitimizing different activities performed in rural areas, such as familiar agroindrustialization. This paper aims to analyze the family agroindustry oriented rural credit policy (Pronaf-agroindustry), evidencing the constitution, elaboration, implementation and results of this line of funding. Moreover, the paper discusses the process of reformulation in the access conditions to the credit during recent years, analyzing the new portfolio constituted by a program called Mais Alimentos. The results of this paper highlight the flexibility of Pronaf-Agroindustry’s financial conditions (reduction of interest rate, increase of the financed ceiling, and spread of the target public), which changes significantly the policy focus (it no longer benefits small family agroindustries exclusively, but also includes major milk cooperatives).

description: A maioria dos estudos de integração de mercados que utiliza a técnica de cointegração com threshold não se preocupa em testar qual o número de regimes de ajustamento de preços é o mais adequado. Neste estudo, utiliza-se um procedimento para determinar o número de regimes estatisticamente indicado para diferentes mercados regionais de carne de frango no Brasil, no período de janeiro de 1998 a junho de 2007. Os resultados mostram que, para um grupo de mercados, o modelo com dois regimes é o mais indicado, enquanto para os demais mercados, o modelo com três regimes é o que melhor se ajusta. Constata-se a presença de significativas barreiras à transmissão de choques de preços entre os mercados, o que provavelmente resulta de custos de transação não desprezíveis na comercialização da carne de frango......Most studies about market integration that use threshold cointegration do not usually test the number of regimes of price adjustment. In this study, we use a testing procedure to determine the number of statistically significant regimes for regional markets of poultry in Brazil in the period of January 1998 to June 2007. Results show that, for some markets, two regimes are adequate, whereas for others, the model should have three regimes. We also conclude that there are important barriers to price transmission among the markets which may come from the existence of high transaction costs regarding trades involving poultry.
Turbulent particle transport in magnetized fusion plasma

description: The understanding of the mechanisms responsible for particle transport is of the utmost importance for magnetized fusion plasmas. A peaked density profile is attractive to improve the fusion rate, which is proportional to the square of the density, and to self-generate a large fraction of non-inductive current required for continuous operation. Experiments in various tokamak devices (AUG, DIII-D, JET, TCV, TEXT, TFTR) have indicated the existence of an anomalous inward particle pinch. Recently, such an anomalous pinch has been unambiguously identified in Tore Supra very long discharges, in absence of toroidal electric field and of central particle source, for more than 4 minutes [1]. This anomalous particle pinch is predicted by a quasilinear theory of particle transport [2], and confirmed by non-linear turbulence simulations [3] and general considerations based on the conservation of motion invariants [4]. Experimentally, the particle pinch is found to be sensitive to the magnetic field gradient in many cases [5, 6, 7, 8], to the temperature profile [5, 9] and also to the collisionality that changes the nature of the microturbulence [10, 11, 12]. The consistency of some of the observed dependences with the theoretical predictions gives us a clearer understanding of the particle pinch in tokamaks, allowing us to predict more accurately the density profile in ITER.

description: A major motivation for building a quantum computer is that it provides a tool to efficiently simulate strongly correlated quantum systems. In this work, we present a detailed roadmap on how to simulate a two-dimensional electron gas---cooled to absolute zero and pierced by a strong transversal magnetic field---on a quantum computer. This system describes the setting of the Fractional Quantum Hall Effect (FQHE), one of the pillars of modern condensed matter theory. We give analytical expressions for the two-body integrals that allow for mixing between $N$ Landau levels at a cutoff $M$ in angular momentum and give gate count estimates for the efficient simulation of the energy spectrum of the Hamiltonian on an error-corrected quantum computer. We then focus on studying efficiently preparable initial states and their overlap with the exact ground state for noisy as well as error-corrected quantum computers. By performing an imaginary time evolution of the covariance matrix we find the generalized Hartree-Fock solution to the many-body problem and study how a multi-reference state expansion affects the state overlap. We perform small-system numerical simulations to study the quality of the two initial state Ansätze in the Lowest Landau Level (LLL) approximation.

Two-photon imaging of glutathione levels in intact brain indicates sites of enhanced redox buffering

Publisher: name: University of British Columbia

description: Oxidative stress, the metabolic imbalance between oxidant creation and destruction is proposed as a final common pathway for neurodegenerative disease and injury. To map sites of antioxidant homeostasis in brain, I used two-photon imaging of monochlorobimane (MCB) fluorescence, a selective enzyme-mediated marker, for reduced glutathione (GSH) in both brain slices and in vivo preparations. I found that cells at the CSF or blood brain interface such as lateral ventricle ependymal cells, meningeal cells, and astroglia contain both high levels of MCB conjugation activity (glutathione S-transferase dependent) and GSH content. In comparison, cortical neurons in Layer II contained approximately 20% of the GSH content of their astrocyte counterparts. Regional mapping of GSH indicated that the highest levels were present in cells lining the lateral ventricles, specifically eperidymal cells and the subventricular zone. The enrichment of GSH content along the lateral ventricle suggested a possible function in oxidant homeostasis for developing neuronal progenitors. Consistent with this, I observed that developing neurons found in the subgranular zone of dentate gyrus, contained 3-fold more GSH than older neurons found in the neighbouring granular layer. Besides imaging GSH distribution with MCB, I also developed an assay to measure different kinetic parameters of GSH metabolism. With this assay, I found that meninges are more active than cortical cells in GSH metabolism. In conclusion, I have developed a powerful approach to map sites of antioxidant homeostasis in brain directly, demonstrating a unique role for GSH in developing neurons and cells at the CSF and blood-brain interface.

description: In this paper we show how a two dimensional fluid model can be used to interpret data obtained from an inclined Mach-probe or a Gundestrup probe. We use an analytical approximation of the solution of the differential equations describing the relation between the plasma flow and the measured ion saturation currents at the probe's surface. The parameters of this analytical solution are determined by comparison with the exact numerical solution of the equations. In this way we are able to measure the parallel as well as the perpendicular Mach numbers over the whole parameter range with a minimum accuracy of 90%.

title: From farm training to therapy : a case study in the history of social work from a macro-micro social policy perspective
Creators: name: Johns, Robert Geraint
Publisher: name: The Open University
Year: 2002

description: This thesis analyses the development of social work during the twentieth century by examining the life history of one residential establishment, Turners Court, founded in 1911. The objective is to explain how ideals and policies are translated into action, by conducting an historical analysis of an organisation that attained some prominence in its field. The thesis sets out evidence to demonstrate that once created, institutions attain an identity and set of values and beliefs of their own, verified through their contribution and response to policy developments. The research draws on insights from current thinking about the macro-micro relationship, relating these to social policy by deploying and evaluating Layder's (1993) multi-perspectival approach that urges greater attention to power, history and general social theory. Turners Court has distinctive features that commend it as a case study. It began as a 'colony' providing men with agricultural training. Its foundations reflected a mix of motives, ranging from the evangelistic to the eugenic. By the 1960s it claimed to be a pioneering institution, yet by the 1980s a substantial contraction in the residential care sector had been set in motion, for reasons analysed in the thesis. In 1991, Turners Court, a 'therapeutic' training establishment for boys aged 14-16, closed. Based on a systematic analysis of archive material, a model of congruence is devised, indicating areas that need to fit for organisations to be created and to survive. Discongruity in these areas is offered to explain their demise. The history of Turners Court, as a microcosm of the history of residential social work, indicates a need to review social policy theory in a way that recognises the importance Of the interplay of macro and micro factors. In particular, more attention needs to be paid to the role of values and belief systems.

A análise dos dados financeiros das cooperativas de crédito, Sociedades de Crédito ao Microempreendedor (SCM) e crédito mútuo compõem o objeto de estudo. A análise foi realizada a partir dos dados de 31/12/2007 disponibilizados pelo Banco Central de 1.439 instituições. Com dados adicionais de 31 instituições liquidadas entre 2003 e 2006, totalizaram-se 1.470 instituições analisadas. Com os valores originais, o banco de dados foi dividido aleatoriamente em duas partes, cada qual com 735 instituições, sendo o primeiro denominado de amostra de desenvolvimento e o segundo, de amostra de validação. A avaliação principal foi feita a partir da Análise Discriminante com os dados obtidos e com padronização. Outras abordagens foram desenvolvidas e comparadas. Os resultados mostram que a segunda abordagem, com padronização e subdivisão das instituições por tamanho (valor do ativo) permite obter resultados mais aprimorados, com Correlação Canônica de 0,994, mostrando que a variável dependente pode ser explicada em 98,8% pelas variáveis independentes. Desta forma, as análises mostram a funcionalidade dessas abordagens como instrumento de classificação, servindo como mecanismo de auxílio aos órgãos reguladores e Cooperativas Centrais no acompanhamento das unidades singulares......This work aims to analyze the financial sustainability of Single Credit Cooperatives of Brazil. The analysis of financial data from credit cooperatives, credit societies of Small Entrepreneur (SCM) and credit make up the mutual object of study. The analysis was performed from the data available from 2007/12/31 by the Central Bank of Brazil of 1,439 institutions. We used indicators of financial structure, assets and the statements of results of those institutions. With additional data from 31 institutions presented between 2003 and 2006, the total is 1,470 institutions analyzed. With the original values, database was divided randomly into two parts, each one with 735 institutions, and the first known sample of development and the second called the validation sample. Other approaches have been developed. The main evaluation was made from the Discriminant Analysis. The results show that the alternative approach with subdivision of standardization and institutions by size (value of assets) to obtain more refined results. Thus, the analysis shows the functionality of these approaches as a tool for classification, serving as a mechanism to help regulatory agencies and the Cooperative Central monitoring of natural units.

description: A growing number of studies have linked facial width-to-height ratio (fWHR) with various antisocial or violent behavioral tendencies. However, those studies have predominantly been laboratory based and low powered. This work reexamined the links between fWHR and behavioral tendencies in a large sample of 137,163 participants. Behavioral tendencies were measured using 55 well-established psychometric scales, including self-report scales measuring intelligence, domains and facets of the five-factor model of personality, impulsiveness, sense of fairness, sensational interests, self-monitoring, impression management, and satisfaction with life. The findings revealed that fWHR is not substantially linked with any of these self-reported measures of behavioral tendencies, calling into question whether the links between fWHR and behavior generalize beyond the small samples and specific experimental settings that have been used in past fWHR research.

The system consists of $M$ uncoupled identical quantum chains. Local control (gates, measurements) is only allowed at the sending/receiving end of the chains. Under a quite general hypothesis on the interaction Hamiltonian of the qubits a theorem is proved which shows that the receiver is able to asymptotically recover the messages by repetitive monitoring of his qubits.

title: Before ethics? : a study of the ethos of the medical profession
Creators: name: Descombes, Christine Ruth Elisabeth Hermine
Publisher: name: The Open University
Year: 2002

description: The thesis makes a distinctive contribution to the field of professional ethics; offering a more nuanced understanding of the role of a profession’s ethos in relation to its ethics. In so doing, it also offers a valuable insight into GP thinking at what proved to be a unique moment in the history of that branch of the medical profession. Using historical and empirical data, the thesis first traces the development of the medical profession’s ethos - Its belief in itself as a noble, superior profession, of special dignity and worth. It then shows the influence of that ethos in areas of professional decision-making that have had a particular impact on the provision of health care within the LJK over the past 50 years. Taking the profession’s ethos as a benchmark, the study explores the nature of the profession’s response to the creation, control and, in recent years, major reform of the NHS which reform introduced a new emphasis on management. The latter provides a case study that relates the theoretical material to an historical situation This includes a number of interviews with GPs that point to the beliefs and values influencing their decisions in relation to the reforms, as they affected general practice. The study concludes that, although a profession dependant on attracting clients may find it necessary to subscribe to a set of ethical principles that draws on outside beliefs and values, it is the ethics derived from its own internal ethos that will take precedence in guiding everyday thinking and practice

title: The history of community care for people with learning difficulties in Norfolk 1930-1980 : the role of two hostels
Creators: name: Rolph, Sheena Elizabeth
Publisher: name: The Open University
Year: 1999

description: This thesis explores the history of community care for people with learning difficulties in Norfolk between 1930 and 1980 through case studies of two hostels. It also examines ways in which people with learning difficulties can make a contribution to a construction of the past. Historical evidence is drawn from biographical and oral history interviews, group discussions and written and photographic archival sources. These methods make it possible to examine the relationship of the hostels to community and institutional care: make comparisons concerning gender, geographical location and culture; and elicit the views of those who had experienced hostel care either as residents or staff. The research showed that though there are many conflicting definitions of community carc, the hostels played a significant role in the development of care in the community in the inter-war period and in the post-war period. The. case studies suggest that community care has a longer history than is usually acknowledged. It was not necessarily the benign alternative to institutional care, but existed as an adjunct to it while retaining a distinctive character. In some respects, hostel developments foreshadowed later policies. The research makes a contribution to the literature on the social history of learning disability; and the methodological literature concerning participatory research.
Anharmonic oscillator driven by additive Ornstein-Uhlenbeck noise

description: We present an analytical study of a nonlinear oscillator subject to an additive Ornstein-Uhlenbeck noise. Known results are mainly perturbative and are restricted to the large dissipation limit (obtained by neglecting the inertial term) or to a quasi-white noise (i.e., a noise with vanishingly small correlation time). Here, in contrast, we study the small dissipation case (we retain the inertial term) and consider a noise with finite correlation time. Our analysis is non perturbative and based on a recursive adiabatic elimination scheme: a reduced effective Langevin dynamics for the slow action variable is obtained after averaging out the fast angular variable. In the conservative case, we show that the physical observables grow algebraically with time and calculate the associated anomalous scaling exponents and generalized diffusion constants. In the case of small dissipation, we derive an analytic expression of the stationary Probability Distribution Function (P.D.F.) which differs from the canonical Boltzmann-Gibbs distribution. Our results are in excellent agreement with numerical simulations.

description: In this paper, we consider triple systems composed of main-sequence (MS) stars, and their internal evolution due to stellar and binary evolution. Our focus is on triples that produce white dwarfs (WDs), where Roche lobe overflow of an evolving tertiary triggers accretion onto the inner binary via a circumbinary disk (CBD) driving it toward a mass ratio of unity. We present a combination of analytic- and population synthesis-based calculations performed using the \texttt{SeBa} code to constrain the expected frequency of such systems, given a realistic initial population of MS triples, and provide the predicted distributions of orbital periods. We identify the parameter space for triples that can accommodate a CBD, to inform future numerical simulations of suitable initial conditions. We find that $\lesssim$ 10\% of all MS triples should be able to accommodate a CBD around the inner binary, and compute lower limits for the production rates. This scenario broadly predicts mergers of near equal-mass binaries, producing blue stragglers (BSs), Type Ia supernovae, gamma ray bursts and gravitational wave-induced mergers, along with the presence of an outer WD tertiary companion. We compare our predicted distributions to a sample of field BS binaries, and argue that our proposed mechanism explains the observed range of orbital periods. Finally, the mechanism considered here could produce hypervelocity MS stars, WDs and even millisecond pulsars with masses close to the Chandrasekhar mass limit, and be used to constrain the maximum remnant masses at the time of any supernova explosion.

description: As fusões e aquisições no Brasil tiveram um grande salto na década de 90 e o setor produtivo da agroindústria da cana-de-açúcar foi um dos destaques. Os efeitos causados no mercado por essas transações podem ser positivos ou negativos, tanto para as empresas diretamente envolvidas como para a sociedade como um todo. Esta pesquisa foi realizada com o objetivo de analisar a concentração de mercado das unidades produtivas e da agroindústria de cana-de-açúcar no Brasil e dos distribuidores de álcool hidratado etílico. Foram utilizados como métodos as taxas de concentração C4, C8, C20 e o Índice de Hirschman-Herfindahl (HHI), além do levantamento de outros estudos e informações em periódicos. As unidades produtivas vêm diminuindo sua concentração, principalmente em função de as empresas de pequeno e médio porte terem aumentado sua escala de produção, sendo, portanto, ainda muito pulverizadas. A agroindústria também se mostrou muito pulverizada, apesar do intenso processo de fusão e aquisição ocorrido entre essas empresas nos últimos anos. Por outro lado, os distribuidores de álcool hidratado etílico vêm apresentando significativa concentração no mercado. Com tudo isso, pode-se dizer que o processo de fusão e aquisição tende a se intensificar entre as unidades produtivas e a agroindústria processadora de cana-de-açúcar no mercado nacional......Mergers and acquisitions in Brazil had improved in the 90’s, and the productive section of the sugarcane agroindustry was one of the highlights. Effects caused by these transactions in the market can be positive or negative for both companies directly involved and the society. The objective of this research is to analyze the market concentration of producing units, the agroindustry of sugarcane and the ethyl hydrous ethanol distributors in Brazil. We have used as methods the concentration rates C4, C8, C20, the Hirschman-Herfindahl Index (HHI), and researches in another studies, journals and newspapers. The productive units have been decreasing their concentration, caused mainly by the increased production scale of the small and medium companies, resulting, therefore, in still very distributive productive units. The agroindustry was also very distributive, in spite of the intense merger and acquisition process that happened among those companies over the last years. On the other hand, distributors of ethyl hydrous ethanol have improved their concentrations in the market. With all this, it can be said that the merger and acquisition process might step up among producing units and the agroindustry which process sugarcane in the domestic market.

description: The most abundant terrestrial lavas, mid-ocean ridge and ocean island basalt (MORB and OIB), are commonly considered to be derived from a depleted MORB-mantle component and more specific, variably enriched mantle plume sources. However, findings of oceanic lavas and mafic cumulates issued from melts, enriched in chlorine and having a radiogenic Sr ratio, can be attributed to an interaction between the asthenosphere-derived melts and lithospheric peridotite variably hydrated due to penetration of hydrothermal water down to and below Moho level. To constrain mechanisms and rates responsible for the interaction, we report results of experiments of reaction between serpentinite and tholeiitic basaltic melt. Results show that the reaction proceeds via a multi-stage mechanism: (i) transformation of serpentinite into Cr-rich spinel-bearing harzburgite containing pore fluid, (ii) partial melting and dissolution of the harzburgite assemblage with formation of interstitial hydrous melts, and (iii) final assimilation of the Cr-rich spinel-bearing harzburgite/dunite and formation of hybrid basaltic melts with high MgO and elevated Cr and Ni contents. Assimilation of serpentinite by basaltic melt may occur under elevated melt/rock ratios and may lead to chromitite formation. Our experiments provide evidence that MORB and high-Mg-Cr orthopyroxene-rich cumulates depleted in incompatible elements can be produced from common mid-ocean ridge basaltic melts modified by reaction with hydrated lithospheric peridotite. We established that the rate of assimilation of serpentinized peridotite is controlled by silica diffusion in the reacting hydrous basaltic melt.

description: Este trabalho analisa as diferenças no estado de saúde entre e dentro dos grupos de ocupados agrícolas e não agrícolas no Brasil, utilizando medidas de autoavaliação do estado de saúde captadas no suplemento da PNAD (Pesquisa Nacional por Amostra de Domicílios) de 2008. As análises baseiam-se na composição socioeconômica dos ocupados agrícolas e não agrícolas e nas estimativas de equações simultâneas para captar as relações não lineares entre saúde, renda e jornada de trabalho. Um dos pressupostos do trabalho é que a baixa prevalência de saudáveis entre os ocupados agrícolas estaria associada, sobretudo, à composição socioeconômica desse grupo, e não à maior insalubridade a que os ocupados das atividades agrícolas estariam submetidos em condições socioeconômicas semelhantes às dos não agrícolas. Analogamente, a desigualdade no estado de saúde seria menor entre os ocupados agrícolas devido aos hábitos mais homogêneos, não só no que se refere ao tipo de atividade, mas também em relação à qualidade de vida e ao acesso a uma série de itens de consumo, típico das localidades menos desenvolvidas onde as atividades agrícolas prevalecem......This paper analyzes differences of health conditions between and within agricultural and non-agricultural workers in Brazil. Self-reported health measures of the Health Supplement of Pesquisa Nacional por Amostra de Domicílios (PNAD), from 2008, are used. Results are based on the description of the socioeconomic characteristics of each group of employees and on estimates of a simultaneous equation to measure non-linear relations between health conditions, income and work hours. The main hypothesis is that the lower prevalence of workers with good health among agricultural workers is mainly due to socioeconomic characteristics of this group and not necessarily to higher insalubrious conditions that such workers would be submitted to in equivalent socioeconomic conditions than non-agricultural workers. Similarly, inequalities in health status within agricultural workers may be lower than non-agricultural workers due to more homogeneous kinds of activities, quality of life and consumption, usually found in less developed areas where agricultural workers prevail.
Examination of the four-fifths law for longitudinal third-order moments in incompressible magnetohydrodynamic turbulence in a periodic box

description: The four-fifths law for third-order longitudinal moments is examined, by the use of direct numerical simulation data on three-dimensional forced incompressible magnetohydrodynamic (MHD) turbulence without a uniformly imposed magnetic field in a periodic box. The magnetic Prandtl number is set to one, and the number of grid points is $512^3$. A generalized Kármán-Howarth-Kolmogorov equation for second-order velocity moments in isotropic MHD turbulence is extended to anisotropic MHD turbulence by means of a spherical average over the direction of $\textbf{r}$. Here, $\textbf{r}$ is a separation vector. The viscous, forcing, anisotropy and nonstationary terms in the generalized equation are quantified. It is found that the influence of the anisotropic terms on the four-fifths law is negligible at small scales, compared to that of the viscous term. However, the influence of the directional anisotropy, which is measured by the departure of the third-order moments in a particular direction of $\textbf{r}$ from the spherically averaged ones, on the four-fifths law is suggested to be substantial, at least in the case studied here.
