This article develops and tests a theory of the institutions that makeproperty rights viable, ensuring their enforcement, mobilizing thecollateral value of assets and promoting growth. In contrast tocontractual rights, property rights are enforced in rem, being affectedonly with the consent of the right holder. This ensures enforcement butis costly when multiple, potentially colliding rights are held in thesame asset. Different institutions reduce the cost of gathering consentsto overcome this trade-off of enforcement benefits for consent costs:recording of deeds with title insurance, registration of rights and evena regimen of purely private transactions. All three provide functionallysimilar services, but their relative performance varies with the numberof transactions, the risk of political opportunism and regulatoryconsistency. The analysis also shows the rationality of allowingcompetition in the preparation and support of private contractswhile requiring territorial monopoly in recording and registrationactivities, this to ensure independence and protect third parties.

Differential distribution and phosphorylation of tau proteins were studied in developing kitten brain by using several antibodies, and was compared to phosphorylation in Alzheimer's disease. Several antibodies demonstrated the presence of phosphorylated tau proteins during kitten brain development and identified pathological structures in human brain tissue. Antibody AD2, recognized tau in kittens and adult cats, but reacted in Alzheimer's tissue only with a pathological tau form. Antibody AT8 was prominent in developing kitten neurons and was found in axons and dendrites. After the first postnatal month this phosphorylation type disappeared from axons. Furthermore, dephosphorylation of kitten tau with alkaline phosphatase abolished immunoreactivity of AT8, but not that of AD2, pointing to a protection of the AD2 epitope in cats. Tau proteins during early cat brain development are phosphorylated at several sites that are also phosphorylated in paired helical filaments during Alzheimer's disease. In either event, phosphorylation of tau may play a crucial role to modulate microtubule dynamics, contributing to increased microtubule instability and promoting growth of processes during neuronal development or changing dynamic properties of the cytoskeleton and contributing to the formation of pathological structures in neurodegenerative diseases.

With the objective of verifying the response of Euterpe oleracea seedlings to seven arbuscular mycorrhizal fungi species, an experimental trial was carried out under greenhouse conditions. Seeds of E. oleracea were sown in carbonized rice husk. Germinating seeds were initially transferred to plastic cups, containing fumigated Reddish Yellow Quartz Sand and inoculated with arbuscular mycorrhizal fungi. Two months later, seedlings were transferred to 2 kg black plastic bags, containing the same soil without fumigation. Plant growth and mineral nutrients were evaluated nine months after mycorrhizal inoculation. Differential effects were observed among the species tested, with Scutellispora gilmorei being the most effective ones in promoting growth and nutrient content of E. oleracea seedlings. The increment resulted from inoculation with S. gilmorei were 92% in total plant height, 116% in stem diameter, 361% in dry matter production, 191% in N, 664% in P, 46% in K, 562% in Ca, 363% in Mg and 350% in Zn contents, comparing to uninoculated controls. Infected root length was positively correlated to nutrient content and plant growth. It was concluded that growth and nutrient uptake of E. oleracea seedlings could be significantly improved by inoculation of effective arbuscular mycorrhizal fungi.

The report of the Steering Committee of the Kerala State Planning Board for the preparation of the VIII five Year Plan on Industry and Hiningzslisted several factors inhibiting and promoting growth of small industrial units. Kerala's educated manpower, the native intelligence of the Keralites best suited for taking up logic—based professions and availability of a Hell—developed and broad~based physical infrastructure particularly in the transport and communications sectors, are a few of the positive factors identified. On the negative side, may be mentioned high wage rates, preference on the part of the educated for white collar Jobs, lack of entrepreneurship, paucity of essential resources for industrial use, high density of population and the distance factor which places Kerala away from the major domestic markets. In this context, it would appear that the industrial co-operative movement could possibly play a vital role in accelerating-the momentum of small industrial development of Kerala which has a Health of highly educated and skilled manpower. However, in spite of the encouragement extended by the Government, the movement does not seem to have.been picking up in the modern small scale sector. The present study is an attempt to analyse the factors that have affected the performance of the industrial co—operatives in the small scale industrial sector of Kerala.

For the past 20 years, the focuses of public health strategies for reducing the risk of cardiovascular disease (CVD) have been aimed at lowering cholesterol levels. However recent findings have highlighted not only cholesterol but also triacylglycerol as a lipid risk factor for CVD. Dietary strategies which are able to reduce these circulating lipid levels, but which are able to offer long-term efficacy comparable with effective drug treatments, are currently being sought. One dietary strategy that has been proposed to benefit the lipid profile involves the supplementation of the diet with probiotics (Part 1), prebiotics and synbiotics (Part 2), which are mechanisms to improve the health of the host by supplementation and/or fortification of certain health promoting gut bacteria. Probiotics in the form of fermented milk products have been shown to have cholesterol-lowering properties, whereas non-digestible fermentable prebiotics have been shown to reduce triacylglycerol levels in animal studies. However in humans studies, there have been inconsistent findings with respect to changes in lipid levels with both prebiotics and probiotics although on the whole there have been favourable outcomes.

In this work we evaluated the ability of different types of antimicrobial peptides to promote permeabilization and growth inhibition of Acanthamoeba castellanii trophozoites, which cause eye keratitis. We used cationic alpha-helical peptides P5 and a beta-hairpin amphipathic molecule (gomesin), of the spider Acanthoscurria gomesiana haemocytes. A. castellanii permeabilization was obtained after 1 h incubation with micromolar concentrations of both types of peptides. While permeabilization induced by gomesin increased with longer incubations, P5 permeabilization did not increase with time and occurred at doses that are more toxic for SIRC cells, P5, however, at doses below the critical dose used to kill rabbit corneal cells was quite effective in promoting growth inhibition. Similarly, P5 was more effective when serine protease inhibitor was added simultaneously to the permeabilization assay. High performance chromatography followed by mass spectrometry analysis confirmed that, in contrast to gomesin, P5 is hydrolysed by A. castellanii culture supernatants. We conclude that the use of antimicrobial peptides to treat A. castellanii infections requires the search of more specific peptides that are resistant to proteolysis.

É feita uma análise da evolução dos conhecimentos sobre as coquinas-reservatório da Formação Lagoa Feia, com base em cinco publicações de geologia de desenvolvimento dos campos de Badejo, Linguado e Pampo. Trata-se de uma única acumulação, onde o controle é misto, ou seja, estrutural, estratigráfico e principalmente diagenético. Falhas antitéticas herdadas do rifteamento pós-basáltico exercem um importante papel no controle das coquinas, promovendo crescimento da seção nos blocos baixos, e servindo de conduto para a circulação de água meteórica, relacionada à discordância pós-coquina que promove dissolução e criação de porosidade secundária nas coquinas. A compreensão do modelo de acumulação do óleo é fundamental tendo em vista oportunidades para projetos de recuperação suplementar de óleo.

In Sub-Saharan Africa, non-democratic events, like civil wars and coup d'etat, destroy economic development. This study investigates both domestic and spatial effects on the likelihood of civil wars and coup d'etat. To civil wars, an increase of income growth is one of common research conclusions to stop wars. This study adds a concern on ethnic fractionalization. IV-2SLS is applied to overcome causality problem. The findings document that income growth is significant to reduce number and degree of violence in high ethnic fractionalized countries, otherwise they are trade-off. Income growth reduces amount of wars, but increases its violent level, in the countries with few large ethnic groups. Promoting growth should consider ethnic composition. This study also investigates the clustering and contagion of civil wars using spatial panel data models. Onset, incidence and end of civil conflicts spread across the network of neighboring countries while peace, the end of conflicts, diffuse only with the nearest neighbor. There is an evidence of indirect links from neighboring income growth, without too much inequality, to reduce the likelihood of civil wars. To coup d'etat, this study revisits its diffusion for both all types of coups and only successful ones. The results find an existence of both domestic and spatial determinants in different periods. Domestic income growth plays major role to reduce the likelihood of coup before cold war ends, while spatial effects do negative afterward. Results on probability to succeed coup are similar. After cold war ends, international organisations seriously promote democracy with pressure against coup d'etat, and it seems to be effective. In sum, this study indicates the role of domestic ethnic fractionalization and the spread of neighboring effects to the likelihood of non-democratic events in a country. Policy implementation should concern these factors.

En cualquier empresa el crecimiento supone una dimensión dinámica, en movimiento más o menos continúo, mientras que el tamaño representa una visión estática de la misma. Desde hace algunos años y en particular en el reciente período (2014-2020) de programación de las políticas de apoyo al desarrollo rural, se está interviniendo sobre el sector cooperativo agroalimentario, priorizando y promoviendo procesos de crecimiento atendiendo al criterio del tamaño en particular. En este trabajo de investigación de Tesis Doctoral se ha querido ahondar en esta cuestión desde un enfoque micro. Para ello se analizan, a nivel de cooperativa, las principales fórmulas de crecimiento desarrolladas por cooperativas hortofrutícolas, no con la pretensión de presentarlo como fenómeno global o receta normativa del cooperativismo agroalimentario, sino como especificidades emergentes del crecimiento cooperativo que no están basados únicamente en el tamaño de las empresas, como a menudo se ilustra desde las administraciones; considerando diversas transformaciones y cambios que estas organizaciones deben desarrollar en el proceso dinámico de crecimiento. Para ello se abordan con una especial atención las implicaciones jurídicas en cada caso y, en este marco, se contemplan diversos estudios vinculados con la evolución de la legislación cooperativa en relación a sus formas de crecimiento en el campo agroalimentario. La contextualización del sector y de los procesos de crecimiento se realiza a nivel europeo y español, prestando especial atención al sector hortofrutícola, para lo cual se han tenido como elementos de apoyo y soporte los informes elaborados dentro del proyecto financiado por la Comisión Europea: Support for Farmers cooperatives (Bijman et al, 2012) y las bases de datos disponibles. El proceso metodológico se ha apoyado en diversas técnicas de investigación social para abordar un análisis empírico a nivel micro basado en tres casos seleccionados como paradigmáticos de integración de cooperativas, sobre los que se realizado una encuesta intensa y un análisis con el Ciclo de Vida de una cooperativa alcanzando resultados sobre la diversidad en las formas de integración y la evolución económico-financiera, social y organizacional que los acompañan, todo ello utilizando una perspectiva histórica de al menos nueve ejercicios ulteriores a los procesos de integración. Las tres cooperativas hortofrutícolas objeto de análisis desarrollan su actividad en el Sureste de la Península Ibérica. Con la identificación de aquellos aspectos más relevantes que pueden haber influido en el desarrollo de estos procesos, el análisis arroja resultados de interés que indican que la legislación actual promueve formas de crecimiento de las cooperativas basadas en la dimensión, sin tener en cuenta otros factores manifiestos de heterogeneidad. La apuesta por la especialización de la empresa cooperativa, incluso recurriendo a la limitación de socios, es una forma de crecimiento sostenible en determinados casos. Como también lo es una mayor implicación de los socios y el desarrollo de mecanismos ágiles para responder rápidamente a los incentivos de un mercado cambiante. La sostenibilidad y la mejora de la salud en los procesos de integración deben apoyarse en mecanismos que generen mayor participación e implicación de su masa social en las estructuras de gobierno para evitar la pérdida de capital social. ABSTRACT In any business growth is a dynamic dimension, in more or less continuous movement, while the size represents a static view of it. In recent years and particularly in the recent period (2014-2020) programming policies to support rural development, are being used to intervene on the agrifood cooperative sector, prioritizing and promoting growth processes by the criterion of size in particular. This research work Doctoral Thesis has aimed to delve into this issue from a micro approach. To this are discussed at the level of cooperative, the main growth formulas developed by a sector of horticultural cooperatives, not with the intention of presenting it as a global phenomenon or policy prescription of the food cooperative, but as emerging specificities of the cooperative growth are not based only in the size of companies, as often it is shown from the authorities, but also consider the transformations and changes that these organizations should develop in the dynamic process of growth. For it dealt with special attention the legal implications in each case and, in this context, they have been contemplated several studies linked to the development of cooperative legislation in relation to their growth forms in the food field. The contextualization of the sector and growth processes is performed at European and state level, paying special attention to horticulture, for which they have been taken as support reports the reports prepared within the project funded by the European Commission: Support for Farmers cooperatives (Bijman et al, 2012) and available databases. The methodology has relied on various techniques of social research to address an empirical micro-level analysis based on three cases selected as paradigmatic integration of cooperatives, on which intensive survey and analysis with the Life Cycle of a cooperative made achieving results on the diversity in the forms of integration and economic and financial, social and organizational evolution that accompany them, all using a historical perspective of at least nine subsequent years to the integration processes. The three analyzed horticultural cooperatives are based in the southeast of the Iberian Peninsula. With the identification of the most relevant aspects that may have influenced the development of these processes, the analysis yields interesting results that indicate that the current legislation promotes growth forms of cooperatives based on the dimension regardless of other factors of apparent heterogeneity or socio-cultural barriers. The commitment to specialization of the cooperative enterprise, including through limiting partners is a form of sustainable growth in certain cases. As it is also a greater involvement of partners and the development of efficient mechanisms to respond quickly to changing market incentives. Sustainability and health improvement in growth processes must rely on mechanisms that generate greater participation and involvement of its membership in the structures of government, to avoid the lost of social capital.

Two bacterial strains that amplified part of the nifH gene, RP1p and RP2p, belonging to the genus Enterobacter and Serratia, were isolated from the rhizoplane of Lupinus albescens. These bacteria are Gram-negative, rod-shaped, motile, facultative anaerobic, and fast-growing; the colonies reach diameters of 3-4 mm within 24 h of incubation at 28 ºC. The bacteria were also able to grow at temperatures as high as 40 ºC, in the presence of high (2-3 % w/v) NaCl concentrations and pH 4 -10. Strain RP1p was able to utilize 10 of 14 C sources, while RP2p utilized nine. The isolates produced siderophores and indolic compounds, but none of them was able to solubilize phosphate. Inoculation of L. albescens with RP1p and RP2p strains resulted in a significant increase in plant dry matter, indicating the plant-growth-promoting abilities of these bacteria.

Maize is among the most important crops in the world. This plant species can be colonized by diazotrophic bacteria able to convert atmospheric N into ammonium under natural conditions. This study aimed to investigate the effect of inoculation of the diazotrophic bacterium Herbaspirillum seropedicae (ZAE94) and isolate new strains of plant growth-promoting bacteria in maize grown in Vitória da Conquista, Bahia, Brazil. The study was conducted in a greenhouse at the Experimental Area of the Universidade Estadual do Sudoeste da Bahia. Inoculation was performed with peat substrate, with and without inoculation containing strain ZAE94 of H. seropedicae and four rates of N, in the form of ammonium sulfate (0, 60, 100, and 140 kg ha-1 N). After 45 days, plant height, dry matter accumulation in shoots, percentage of N, and total N (NTotal) were evaluated. The bacteria were isolated from root and shoot fragments of the absolute control; the technique of the most probable number and identification of bacteria were used. The new isolates were physiologically characterized for production of indole acetic acid (IAA) and nitrogenase activity. We obtained 30 isolates from maize plants. Inoculation with strain ZAE94 promoted an increase of 14.3 % in shoot dry mass and of 44.3 % in NTotal when associated with the rate 60 kg ha-1 N. The strains N11 and N13 performed best with regard to IAA production and J06, J08, J10, and N15 stood out in acetylene reduction activity, demonstrating potential for inoculation of maize.
