Focamos as instituições de ensino e extensão rural no Brasil como atores da construção da identidade social do agricultor introduzindo-o no espaço dos mercados como um empreendedor. A partir da perspectiva do caráter performativo da economia, confrontamos esta construção com a atuação dos EUA através do acordo MEC-USAID e o ponto de passagem de um modelo de relação Estado/mercado na lógica da hierarquia do keynesianismo para a lógica do mercado inaugurada pelo Consenso de Washington. O pós-guerra vislumbrou um acordo cognitivo em torno de um agricultor pensado como um empreendedor e a missão da agricultura era a de salvar os famintos. No início do século XXI predomina a lógica da financeirização que atinge o rural através da linguagem das commodities agrícolas. Destaca-se na paisagem rural um pequeno agricultor e é ele mesmo o faminto; a extensão rural assume um caráter assistencial
We focus on the educational and rural extension institutions in Brazil as agents of the farmer’s social identity, inserting him as an entrepreneur in the market field. From the point of view of the performative character of economics, we confront this model with the USA acting through the MEC-USAID agreement and the turning point of a model of State-market relations according to the keynesian hierarchical logic to the market logic inaugurated by the Washington Concensus. During the post war period, the USA/USSR polarization permitted a cognitive agreement about a farmer as an entrepreneur and the agriculture mission was to save the hungry. At the beginning of the 21st century, the financialization logic that reaches the rural through the language of the agricultural commodities prevails. The small farmer is himself the hungry one and the rural extension assumes na assistental character

Opis:
The increasing needs of using aluminum epoxy composite as a replacement to solid metal rapid prototyping has opened to interests in optimizing its machining processes. This paper reported on the success of optimizing the surface roughness of aluminium epoxy composite using milling process along with a new finding on the best combination parameters. Taguchi method was used as the optimization method whereas spindle speed, feed rate, and depth of cut were set as input factors using an L9 Orthogonal Array. Analysis of Variance was used to identify the significant factors influencing the surface roughness. Experiment was conducted in dry condition using a vertical milling machine and the surface roughness after the machining was evaluated. Optimum combination of cutting parameters was identified after the finest surface roughness (response) based on the signal-to-noise ratio calculated. Cutting parameters selected after preliminary testing are cutting speeds of (2000, 3000 and 4000) rpm, feed rate (300, 400 and 500) mm/min, and cutting depth (0.15, 0.20, and 0.25) mm. The result showed that cutting speed had the largest percentage contribution to surface roughness with 69% and the second highest contribution was feed rate with 22% and depth of cut at 9%. The spindle speed was found as the most significant factor influencing the quality of surface roughness. The result is significant particularly in providing important guidelines for industries in selecting the right combination of parameters as well as to be cautious with the most significant factor affecting the milling process of metal epoxy composite.

Opis:
This article aims at analyzing the main features of Donald Trump´s trade policy towards Mexico. Based on the deterioration of the trade conditions reflected through the exchange rate volatility, as well as the main clauses signed in the USMCA, this paper identifies several factors that play a decisive role in determining the new protectionism and nationalism in the US foreign policy. Among others are the US-China trade war, demographic changes, migration and the Mexican export competitiveness. We conclude that Mexico accepted conditions through the USMCA that may have helped to meet Trump´s demands in the short term, but they could lead to a bottleneck in the medium and long term.
El presente artículo tiene como objetivo principal analizar las principales características del comercio México-Estados Unidos de América (EUA) bajo el liderazgo de Donald Trump. Partiendo del enrarecimiento de la relación comercial reflejada en la volatilidad del tipo de cambio y los compromisos acordados en el T-MEC, se resaltan los factores que determinan el nuevo proteccionismo-nacionalismo de los Estados Unidos. En este contexto, la guerra comercial con China, cambios demográficos, migración y la estructura del sector externo mexicano juegan un papel fundamental. Se concluye que, dada la dependencia económica de México con respecto a los Estados Unidos, México se ha visto en la necesidad de aceptar condiciones que en el corto plazo parecen satisfacer las demandas de Trump, pero que podrían significar un estrés aún mayor en el mediano y largo plazos.

Opis:
The possibilities of simultaneous removal of sulfates and heavy metals (Cu, Ni, Zn) from acid mine drainage have been investigated in two-section bioelectrochemical system (BES). The used BES is based on the microbial sulfate reduction (MSR) process in the anode zone and abiotic reduction processes in the cathodic zone. In the present study, the model acid mine drainage with high sulfate (around 4.5 g/l) and heavy metals (Cu2+, Ni2+ and Zn2+) content was performed. As a separator in the laboratory, BES used an anionic exchange membrane (AEM), and for electron donor in the process of microbial sulfate reduction in the bioanode zone – waste ethanol stillage from the distillery industry was employed. In this study, the possibility of sulfates removal from the cathodic zone was established by their forced migration through AEM to the anode zone. Simultaneously, as a result of the MSR process, the sulfate ions passed through AEM are reduced to H2S in the anode zone. The produced H2S, having its role as a mediator in electron transfer, is oxidized on the anode surface to S0 and other forms of sulfur. The applicability of waste ethanol stillage as a cheap and affordable organic substrate for the MSR process has also been established. Heavy metals (Cu2+, Ni2+ and Zn2+) occur in the cathode chamber of BES in different degrees of the removal. As a microbial fuel cell (MFC) operating for 120 hours, the reduction rate of Cu2+ reaches 94.6% (in waste ethanol stillage) and 98.6% (in the case of Postgate culture medium). On the other hand, in terms of Ni2+ and Zn2+, no significant decrease in their concentrations in the liquid phase is found. In the case of microbial electrolysis cell (MEC) mode reduction of Cu2+– 99.9%, Ni2+– 65.9% and Zn2+– 64.0% was achieved. For 96 hours, the removal of sulfates in MEC mode reached 69.9% in comparison with MFC mode – 35.2%.

Opis:
Artykuł przedstawia pracę Biskupiego Komitetu Pomocy Osobom Pozbawionym Wolności i ich Rodzinom w Diecezji Koszalińsko-Kołobrzeskiej. W działalność zaangażowane były osoby duchowne i świeckie. Praca podzielona była na trzy rejony (koszaliński, słupski i szczecinecki). Nad całością czuwał biskup Ignacy Jeż, który również uczestniczył w całym dziele. Odprawiano msze święte, gdzie modlono się za pokrzywdzonych. Organizowano zbiórki pieniężne na paczki żywnościowe i artykuły pierwszej potrzeby. Istotą było również podnoszenie ludzi na duchu. Osoby zaangażowane zbierały informacje na temat potrzebujących, rozdzielały żywność i leki, które głównie pochodziły z darów zagranicznych. Organizowano dla rodzin i ich dzieci akcje wakacyjne. Jedną z potrzeb była również pomoc prawna i finansowa. Osoby zaangażowane jednoczył jeden cel, bezinteresowna pomoc drugiemu człowiekowi.
The article presents the work of the Bishop’s Committee for Aid People Deprived of Freedom and Their Families in the Koszalin-Kolobrzeg (Kołobrzeg) Diocese. Clergy and lay people were involved in the activity. All the works were divided into three regions (Koszalin, Slupsk (Słupsk) and Szczecin). Bishop Ignacy Jeż, who also participated in the whole work, supervised the whole project. Holy masses were celebrated, where people prayed for the aggrieved. Money collections were organized for food parcels and basic necessities. It was also essential to lift people’s spirits. The people involved collected information about those in need, distributed food and medicines, which came mainly from foreign donations. Holiday campaigns were organized for families and their children. One of the needs was also legal and financial assistance. The people involved were united by one goal, selfless help to another person.
