In this paper it been analyzed the possible relation between violence and the lack of property right in the slum areas of the old quarters. It been said that the Law does not just a system of the exercise of coercion, but an order of justice generation which realization is assisted by tools. One of them is the property system. This is a space by which State give support to people to achieve their life goals. In this way, if it would been known the danger that involves the existence of precarious houses and if it would been identify the groups who live there, it would be easy a redefinition of the property rights and an urban renewal. It understood the energy with the violence to explain how it appears in the society. Likewise, it been said that while more efficient and rightful be a normative process that support the property system, the agents will put their effort to find the common go...

“Joints and Problems of Property according to Hegel”. Hegel’s theory of property according to the person’s abstract law in his Philosophy of Law states (a) that property is the external objectification of free will through appropriation (common or private) of exterior things; (b) that property does not only refer to a previously given world, but also to the absolute difference between persons and things and to the proto-economic problem of the persons’ access to things through their actions; (c) that the property that is rationally necessary for the free person-hood supposes the recognition between self-consciousness (even so the notions of recognition and objective spirit be improvable constructions with a detailed analytics both philosophical and empirical); and (d) that property, without refusing the typical formalism of private law, demands the concrete universality of publ...

Edible films for packaging and plastic material replacement purposes are produced based on biodegradable raw materials such as polysaccharides and agents with biological properties, making the final product an alternative for the protection and extension of the shelf life of foods. The main objective of the present research was to evaluate the antioxidant and antimicrobial activity of chitosan biofilms functionalized with muña essential oil. For this purpose, 12 edible films were formulated with 3 concentrations of chitosan (1, 2 and 3%) and 3 of essential oil (0.5, 2 and 5%) including chitosan-only blanks. The antioxidant activity evaluated in biofilms with a higher content of muña essential oil presents more than 60% of DPPH free radical uptake, while in the antimicrobial activity evaluated by petri dishes grown with Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli...

Muscle proteins of Dosidicus gigas mantle have great techno-functional advantages and during their processing at industrial level considerable discards of muscle proteins are generated and used to elaborate meals with low added value. The aim of the study was to evaluate the effect of hydrolysis time on the techno-functional properties and antioxidant capacity of jumbo squid. Mantle muscle protein discards were cooked, ground and subjected to enzymatic hydrolysis (Protamex ©) for 1, 2, 3, 4, 5 and 6 hours at 58 ° C; ratio of water: substrate 1: 1. The hydrolysis reaction was stopped at 90 ° C for 5 minutes and then were filtrate. Hydrolyzed solutions (2% of dissolved solids) in established times were taken and their techno-functional properties such as foaming, emulsifying, antioxidant capacity and degree of hydrolysis were determined.

Context: Ceramic veneers are shown as an excellent alternative to improve dental aesthetics with ideal optical and mechanical properties. The objective of this study, was to evaluate the influence of the cementing agent and artificial aging on the veneer´s color. Material and Methods: For this, 30 human premolars were carved to receive veneers made with 0.5mm thick porcelain of the same color. The tooth-veneer sets were randomly separated into three groups (n = 10). A first color measurement was performed on each tooth using the Vita Easyshade colorimeter. The cementing process was carried out according to the group, with RelyX ultimate cement, RelyX Veneer and Tetric-N-Flow fluid resin; performing the color measurement. After heat aging treatment, the sets were subjected to a new color evaluation. Results: The data obtained from the measurements, were analyzed by ANOVA with Games - How...

El presente trabajo de investigación tuvo como objetivo complementar la Ley 29080 para determinar la responsabilidad civil del agente inmobiliario frente al tercero que contrata en virtud de la información que este le proporciona, cuyo objetivo es brindar una mayor seguridad jurídica en las transacciones de bienes inmuebles, puesto que en la actualidad el fraude inmobiliario es la principal amenaza para el mercado inmobiliario y por lo tanto, también para los agentes inmobiliarios. Por tales motivos, ha sido de gran necesidad analizar fuentes del Derecho Comparado donde si se regule la responsabilidad civil del agente inmobiliario para estos casos, es así que como principales fuentes tenemos la normativa Española y Ecuatoriana. De tal modo, que al aplicar un metodo de carácter social y jurídico nos permitirá desarrollar cuáles son las medidas que el Perú debe adoptar para esta...

Probiotic bacteria in aquaculture represent a control alternative and prevention of pathogens, in addition, reduce the use of antibiotics. However, it is necessary to search for other groups of bacteria with similar or better properties, obtained even from the same source. The aim of the study was to identify molecularly lactic acid bacteria with probiotic properties isolated from the posterior intestine of Nile tilapia (Oreochromis niloticus). The study was carried out from November 2017 to March 2018 evaluating the antagonistic, proteolytic, amylolytic, and antibiotic sensitivity activities, and antagonistic to the following pathogens: Aeromonas hydrophila, Aeromonas veronii, Pseudomonas aeruginosa, Pseudomonas putida and Plesiomonas shigelloides. It was identified by sequencing the 16S rRNA gene that Enterococcus faecium (IP5-2a) and Pedioc...

Wood plastic composites of recycled polypropylene PPr and Pinus elliottii (PIE) were developed using soybean oil, stearic acid, caprylic acid and itaconic acid grafted with polypropylene (PPgAI) as coupling agents. The composites were processed in a co-rotating twin screw extruder and injection molded. The materials were characterized by mechanical properties, thermogravimetric analysis, morphological, physical and contact angle. The results showed that soybean oil acted as a plasticizer and reduced mechanical properties of composites. On the other hand, the addition of stearic acid, caprylic acid and PPgAI resulted in an increase in flexural strength of 8, 20 and 29%, respectively, when compared to the composite without compatibilizer. The composites developed with coupling agent commonly used, polypropylene grafted with maleic anhydride (PPgAM) had a 35% increase in flexural strength. ...

In order to improve the organoleptic properties of giant corn fried snack, the effects of chemical peeling agent type (CaOH or NaOH), immersion in peeling solution, cooking time, and grain moisture content before frying, were studied. NaOH was found to be more effective than CaOH as a peeling agent of corn. Nixtamalization flavor was best developed and a lighter snack color was obtained when corn grains were immersed in the peeling solution of NaOH for 6 h. A longer cooking time (0, 8, 16 min) yielded a larger grain expansion. By adjusting grain moisture content (before frying) by drying, the texture of the snack could be controlled. High moisture contents, > 42 % (w.b.) produced crunchy but hard-textured snacks; whereas, low moisture contents, < 26 % (w.b.) gave soft but dry-textured snacks. Therefore, in order to obtain crunchy but soft snacks, moisture content must be adjusted t...

β-Amyloid (Aβ) is a toxic peptide that has a high propensity for aggregation, and it is often present in the brains of patients with Alzheimer's disease (AD). Bioactive compounds from medicinal plants with neuroprotective properties are of interest in protecting against toxic forms of the Aβ peptide. In the present work, we evaluate the in vitro antiaggregant / disaggregating capacity of amyloid and amyloid-type aggregates by the anthocyanins of Zea mays L. (purple corn). Using the differential pH method, we quantified the total anthocyanin content. With the help of spectrophotometric readings of the amyloid-like protein-Congo Red and Aβ-Congo Red complexes, we evaluated the antiaggregation and disaggregation effects of anthocyanins on amyloid peptides and amyloid derivatives. The results showed a significant activity of antiaggregant / disaggregating capacity by anthocyanins, (33.54...
