John Stuart Mill e o cultivo da individualidade

The development of a human individual was a matter of investigation for many thinkers through the history of philosophy. The meanings that this development has taken were, nevertheless, very diversified, involving moral, political, epistemological, aesthetical and even religious aspects. The main agents in this process of development of human individuality are, on the one hand, each individual, who has to strive to improve himself the most, creating and resorting to the means available to that; on the other hand, the fomentalist State also have to take his part in this process, given that such a State has a direct interest in the development of his own citizens; it has to act in such a way that it can foment new and enhance the old existing means that can be used to accomplish the task of developing the human individuality. The goal of this thesis is to investigate the meaning that such development has acquired for the utilitarian philosopher John Stuart Mill, from his conception of individuality.

FEM Analysis to Optimally Design End Mill cutters for Milling of Ti-6Al-4V

This paper presents an FEM analysis conducted for optimally designing end mill cutters through verifying the cutting tool forces and stresses for milling Titanium alloy Ti-6Al-4 V. Initially, the theoretical tool forces are calculated by considering the cutting edge on a cutting tool as the curve of an intersection over a spherical/flat surface based on the model developed by Lee & Altinas [1]. Considering the lowest tool forces the cutting tool parameters are taken and optimal design of end mill is decided for different sizes. Then the 3D CAD models of the end mills are developed and used for Finite Element Method to verify the cutting forces for milling Ti-6Al-4 V. The cutting tool forces, stress, strain concentration (s), tool wear, and temperature of the cutting tool with the different geometric shapes are simulated considering Ti-6Al-4 V as work piece material. Finally, the simulated and theoretical values are compared and the optimal design of cutting tool for different sizes are validated. The present approach considers to improve the quality of machining surface and tool life with effects of the various parameters concerning the oblique cutting process namely axial, radial and tangential forces. Various simulated test cases are presented to highlight the approach on optimally designing end mill cutters.

Finite element analysis of hot rolling in the blooming mill

During this thesis work a coupled thermo-mechanical finite element model (FEM) was builtto simulate hot rolling in the blooming mill at Sandvik Materials Technology (SMT) inSandviken. The blooming mill is the first in a long line of processes that continuously or ingotcast ingots are subjected to before becoming finished products. The aim of this thesis work was twofold. The first was to create a parameterized finiteelement (FE) model of the blooming mill. The commercial FE software package MSCMarc/Mentat was used to create this model and the programing language Python was used toparameterize it. Second, two different pass schedules (A and B) were studied and comparedusing the model. The two pass series were evaluated with focus on their ability to healcentreline porosity, i.e. to close voids in the centre of the ingot. This evaluation was made by studying the hydrostatic stress (σm), the von Mises stress (σeq)and the plastic strain (εp) in the centre of the ingot. From these parameters the stress triaxiality(Tx) and the hydrostatic integration parameter (Gm) were calculated for each pass in bothseries using two different transportation times (30 and 150 s) from the furnace. The relationbetween Gm and an analytical parameter (Δ) was also studied. This parameter is the ratiobetween the mean height of the ingot and the contact length between the rolls and the ingot,which is useful as a rule of thumb to determine the homogeneity or penetration of strain for aspecific pass. The pass series designed with fewer passes (B), many with greater reduction, was shown toachieve better void closure theoretically. It was also shown that a temperature gradient, whichis the result of a longer holding time between the furnace and the blooming mill leads toimproved void closure.

Cryopreservation of avocado (Persea Americana Mill.) using somatic embryos

Avocado genetic resources are currently maintained in the form of field repositories at great cost and risk of natural disasters, pest and diseases. Cryopreservation offers a necessary, complimentary method that is safe, cost-effective and long-term. However, long-term maintenance and regeneration of plantlets from avocado somatic embryos has been a major barrier in the development of new avocado cultivars. In this study, two protocols for vitrification-based cryopreservation of avocado somatic embryos were investigated. Globular somatic embryos of two avocado cultivars were tested, revealing cultivar-dependent differences in desiccation tolerance and subsequent freezing resistance, possibly attributed to their size and culture age. A two-step regeneration system, involving an intermediate liquid phase step between subcultures in solid medium, significantly enhanced shoot development from somatic embryo tissue. This work will add considerable value towards cryopreservation of avocado somatic embryos for germplasm conservation and the generation of new and improved avocado cultivars.

Comparative study of bioactive potential of Fueniculum vulgare Mill. and Matricaria recutita L. phenolic rich extracts to functionalize cottage chesse

Synthetic additives used in a wide variety of food products have been associated to some toxic effects. This conducted to an increasing interest of consumers for natural additives, including food preservers [1]. Many aromatic herbs have been used to prepare bioactive extracts with benefits to the consumer's health. Foeniculum vulgare Mill. (fennel) and Matricaria recutita L. (chamomile) are examples of popular herbs rich in phenolic compounds with documented antioxidant and antimicrobial properties [2,3]. The present work confirms the antioxidant (DPPH scavenging activity, reducing power and lipid peroxidation inhibition) and antimicrobial (against bacteria such as Bacillus cereus and Salmonella Typhimurium and fungi such as Aspergillus niger, A. versicolor and PenicilliumfimicuJosum) activities of fennel and chamomile extracts, obtained by decoction. The chemical characterization of the extracts, performed by HPLC-DAD-ESIIMS, revealed the presence of five flavonoids (mainly qercetin-3-0- glucoside) and twelve phenolic acids (mainly 5-0-caffeolyquinic acid) for fennel extract and the presence of nine flavonoids (mainly luteolin-0-glucuronide) and ten phenolic acids (mainly di-caffeoyl-2,7- anhydro-3-deoxy-2-octulopyranosonic acid) for chamomile extract. Due to their high antioxidant and antimicrobial activities, both extracts were then incorporated (at DPPH scavenging activity EC25 value: 0.35 mg/mL and 0.165 mg/mL for fennel and chamomile, respectively) in cottage cheeses (prepared by Queijos Casa Matias Lda) as natural additives with two objectives: to increase the shelf-life of the cottage cheeses and to provide bioactive properties to the final products. The results showed that the use of these natural extracts did not alter significantly the nutritional characteristics of the cottage cheese in comparison with control samples (cottage cheese without extracts), but improved its antioxidant potential (more evident in the samples with chamomile extract). After 14 days of storage, only the control samples showed signs of degradation. Overall, the present study highlights the preservation potential of fennel and chamomile extracts in cottage cheeses, improving also their bioactivity.

Foeniculum vulgare Mill. as a natural ingredient to improve cottage cheese antioxidant properties

Food industry is focused on the development of novel functional foods containing health promoting natural ingredients. Natural antioxidants present important health benefits like the prevention of several diseases related to oxidative stress [1,2]. Foeniculum vulgare Mill. (fennel) is a source of those compounds with proved antioxidant potential [3]. Herein, after evaluation of 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity and reducing power of fennel (provided by Américo Duarte Paixão Lda.) decoction, we propose its incorporation into cottage cheese (produced by Queijos Casa Matias Lda.). Three groups of cottage cheese samples were prepared: control; samples with fennel decoction (incorporated at EC25 value=0.35 mg/mL, previously determined by DPPH assay); and samples with fennel powder (incorporated at 1.75 mg/mL, considering the decoction yield=20%). The samples were submitted to an evaluation of DPPH scavenging activity and reducing power immediately after the incorporations, and after 7 and 14 days of storage, at 4 ºC. The incorporation of fennel improved the antioxidant activity of cottage cheese. Samples incorporated with plant powder revealed higher antioxidant properties than samples incorporated with decoction, either in 0 or 7 days of storage. After 14 days, cottage cheese incorporated with fennel decoction gave the highest DPPH scavenging activity (46.72±0.09 mg/mL). A decrease in the antioxidant potential of the cottage cheese with fennel was observed along the shelf life. Nevertheless, it is important to highlight that the samples still display antioxidant properties. Studies regarding the effects of the incorporation of these natural ingredients on nutritional and chemical composition of cottage cheese are in course

Levels of some heavy Metals in Cocoyam ( Colocasia esculentum ) grown on Soil receiving Effluent from a Paint Industry

The levels of some heavy metals in soil samples and tubers of cocoyam ( Colocasia esculentum ) grown on soil receiving paint wastes (PWS) has been investigated using Atomic Absorption spectrophotometer (Unicam 939/959 model). Similar analyses were carried out for the same plant from a control area. The studies revealed that although the P.W.S contained abnormally high levels of Pb (474.14mgkg-1) and Cu (137.85mgkg-1). The paint waste tuber (PWT) recorded low levels of these metals: Pb (2.13mgkg-1) and Cu (13.85mgkg-1) respectively. Correlation analysis tested at 0.05 level of significance show that no significant correlation existed between the metals levels in the soil and the level in the tuber. In all cases the levels of the metals in the tubers were well below the upper limit documented for unpolluted plant. The results however suggest the ineffectiveness of the use of Colocasia esculentum as a bioindicator for heavy metal pollution in soil.

Genetic diversity assessment of the almond (Prunus dulcis (Mill.) DA Webb) traditional germplasm of Algarve, Portugal, using molecular markers

In this study, 123 almond (Prunus dulcis (Mill.) D. A. Webb) trees identified among traditional orchards in the Algarve region and 53 trees of the local field collection managed by the regional office of the Portuguese Ministry of Agriculture (DRAALG) were assessed using isozyme, inter- single sequence repeat and simple sequence repeat or microsatellite techniques for the evaluation of genetic diversity and genetic relatedness and identification of new accessions for the field collection. The isozyme analysis allowed the distribution of the 176 plants into 13 different classes of enzyme similarity, while the use of DNA markers increased the distribution of the analysed trees among 140 discriminating DNA patterns. Multiple cases of homonymy and synonymy were identified in the local germplasm. Some traditional varieties, such as Lourencinha, appeared to be relatively homogeneous, while other local denominations, e.g. Galamba, included diverse genotypes. Of the 13 commercial varieties analysed in this study, 11 assembled in one major cluster clearly differentiated from the majority of the local genotypes. These results reinforced the perception that the Algarve traditional germplasm constitutes an important repository of genetic diversity, eventually carrying alleles of high agricultural interest such as the recently identified Phomopsis resistance in the traditional variety Barrinho Grado.

Formulación bioinsecticida a partir del aceite esencial de ambrosia arborescens mill (altamisa) de aplicación canina

La presente investigación se planteó reemplazar el uso de insecticidas sintéticos, formulando un champú bioinsecticida de aplicación canina mediante la acción biocida del aceite esencial deAmbrosia arborescens Mill (Altamisa). La planta se recolectó en las laderas del rio Tomebamba, cercanas al Campus Balzay de la Universidad de Cuenca Parroquia San Joaquín. La recolección se realizó durante los meses de Enero a Marzo del 2016. El desarrollo y formulación del producto se realizó en el Laboratorio de Biotecnología, Facultad de Ciencias Químicas de la Universidad de Cuenca. La obtención del aceite esencial de A. arborescens se realizó mediante hidrodestilación por el método Clevenger, con un rendimiento del 0,14%. La actividad biocida se estableció en un ensayo “in vitro” ante el nematodo Panagrellus redivirus, determinándose la dosis letal (DL50) de 250 uL/mL. Debido a la moderada DL50y bajo rendimiento, se planteó como estrategia, determinar el DL50 del extracto orgánico de A. arborescens, el cual se obtuvo mediante una extracción con metanol, consiguiendo un rendimiento del 2 % y DL50de 31,25 uL/mL. De acuerdo estos resultados se procedió a realizar pruebas en pulgas de perros(Ctenocephalides canis) con el extracto de A. arborescens, estableciendo una efectividad del 100 % a la concentración de 46,875 mg/mL en el periodo de tiempo más corto, siendo esta la dosis aplicada para la formulación del champú. El extracto metanólico de A. arborescens presentó elevada actividad biocida, comparado con el aceite esencial. Esta sustancia activa es promisoria en la formulación de bioinsecticidas para mascotas.

From Mill Gates to Magic City: U.S. Steel and Welfare Capitalism in Gary, Indiana, 1906-1930

Gary, Indiana is a city with indelible ties to industrial paternalism. Founded in 1906 by United States Steel Corporation to house workers of the trust’s showpiece mill, the emergence of this model company town was both the culmination of lessons learned from its predecessors’ mistakes and innovative corporate planning. U.S. Steel’s Progressive Era adaptation of welfare capitalism characterized the young city through a combination of direct community involvement and laissez-faire social control. This thesis examines the reactionary implementation of paternalist policies in Gary between 1906 and 1930 through the purviews of three elements under corporate influence: housing, education, and social welfare. Each category demonstrates how both the corporation and citizenry affected and adapted Gary’s physical and cultural landscape, public perceptions, and community identity. Parallel to the popular narrative throughout is that of Gary’s African-American community, and the controversial circumstances of this population’s segregated development.
