Factores económicos y extraeconómicos de la renta de la tierra en la interfase rural-urbana del Gran Buenos Aires (1994-2014)/ Economic and extra-economic factors of land rent in the rural-urban interface of Greater Buenos Aires (1994-2014)
Authors: González Maraschio Fernanda 
Published: December 2018

Se estudian los procesos que determinan los usos del territorio en cuatro partidos que conforman un ámbito de interfase rural-urbana al oeste del Gran Buenos Aires. Se trata de un espacio de continuidad e integración entre el campo y la ciudad, con eje en la ruta nacional 7, donde se desarrollan de manera simultánea actividades y usos correspondientes a los procesos contrapuestos de urbanización expandida, provenientes de la ciudad primada, y de agriculturización/oleaginización, que se extienden desde la zona núcleo de la agricultura. Estos frentes de expansión del capital contraponen modalidades de ocupación y apropiación del espacio, configurando un espacio heterogéneo y conflictivo a partir de las transformaciones en los usos tradiciones del territorio, así como de la aparición de nuevas actividades, cuyo dinamismo está estrictamente condicionado por su rentabilidad. El objetivo del artículo es analizar los factores económicos y extraeconómicos que conforman la renta de la tierra y su impacto en la evolución de los precios en dólares por hectárea, entre 1994 y 2014. Para ambos casos, se encontró que la intensificación del capital y la valorización paisajística son los factores destacados, lo cual se refleja en un incremento promedio del 500% en el precio de la tierra de toda la zona.
Abstract
The article studies the processes that determine the uses of the territory in four parties that make up an area of ??rural-urban interface in the west of Greater Buenos Aires. It is a space of continuity and integration between the countryside and the city, with axis in the national route 7, where activities and uses corresponding to the opposed processes of expanded urbanization, coming from the primate city, and of agriculturization/oleaginization, which extend from the core zone of agriculture, are developed simultaneously. These fronts of expansion of capital oppose modalities of occupation and appropriation of space, configuring a heterogeneous and conflictive space from the transformations in the traditional uses of the territory, as well as the appearance of new activities, whose dynamism is strictly conditioned by its profitability. The objective of the article is to analyze the economic and extra-economic factors that make up the income of the land and its impact on the evolution of prices in dollars per hectare, between 1994 and 2014. In both cases, it was found that the intensification of capital and landscape enhancement are the outstanding factors, reflected in an average increase of 500% in the price of land throughout the area.

Published: December 2018

Aim of study: The objectives of this research were to determine the effectiveness of
melamine impregnated paper (MIP) waste as an adhesive in the particleboard
manufacturing and effects of the MIP waste using as an adhesive on the some
technological properties of particleboard.

Area of study: To determine the mechanical, physical and formaldehyde
content of particleboards manufactured with different resins (MIP waste, neat
MIP resin).

Material
and Methods: In this study, particleboards were produced with utilizing MIP waste and
neat MIP resin. No additional adhesive was used for MIP waste. Two different
types of mixture of Turkish red pine (90%) and poplar wood (10%) particles
(fine and coarse) were used. Eight different particleboard
groups and three particleboards with three layers (two surface layers and one
core layer) were manufactured for each group in hot press.

Main
results:
As results of this
study, amount of adhesives had significant effect on panel properties. With the
increasing of both adhesive rates (MIPW and neat MIP resin), mechanical and
physical properties of particleboard were improved. However, formaldehyde
content values were worsen with the increasing
of both adhesive rates. The best result for MIPW and neat MIP resin were
obtained when highest rates of them (25% and 13%, respectively) were used.

Research
highlights:
Particleboards were successfully manufactured with using of the MIP waste as
adhesive. Although the MIPW (25%) boards were provided lower mechanical and
physical values than neat MIP resin (13%) boards, they were satisfied the most
of standard requirements.

Published: December 2018

Background: Gastric cancer (CG) is the fifty most common cancer among males and seventh most common cancer among females in India. Prognosis in gastric cancer is very much related to pathological staging. Over the last decade management of gastric cancer has evolved from surgeon to multidisciplinary approach. Laparoscopy has been proposed as an accurate staging modality in a variety of upper gastrointestinal malignancies.Methods: The present cross-sectional prospective hospital-based study was conducted in the department of surgery, pt. J.N.M medical college Raipur, Chhattisgarh, India, during study period July 2016 to June 2018. All the patients of endoscopic biopsy proven gastric cancer (50 cases) who presented during study period and satisfied the inclusion criteria underwent investigations like hemogram, renal function tests, liver function tests, CEA, CA 19-9, chest X-ray, CECT Abdomen and pelvis, staging laparoscopy. Standard protocols were followed for CECT abdomen scan, staging laparoscopy. Appropriate management of the cases were done.Results: In this study, most common symptom associated with carcinoma stomach was upper abdominal pain which was present in 42 cases (84%). Most common site for tumor was pylorus in 38 cases (76%). 2nd most common site for tumor was fundus in 8 cases (16%) followed by body in 3 cases (6%) and diffuse in 1 case (2%). CECT staged 2 cases (4%) as stage I (IA-0, IB-2), 11 cases (22%) as stage II (IIA-3, IIB-8) and 37 cases (74%) as stage III (IIIA- 18, IIIB-05, IIIC-14). Surgery with curative intent was done in 15 cases (30%). In 32 cases (64%) due to disseminated disease as found on staging laparoscopy, surgery was abandoned and patients were sent for Neoadjuvant chemotherapy.Conclusions: Laparoscopy is a valuable technique in staging carcinoma stomach and has an important role in detection of occult extensive intra-abdominal or metastatic disease.

Authors: KAYA İrfan 
Published: December 2018

The objective
of the present study is to characterize the mechanical behavior of laminated
metal composites (LMCs) that consist of commercially pure titanium and 1100
aluminum layers which were ultrasonically consolidated. Ultrasonic consolidation is a low temperature
process used to fabricate layered solid metal structures. Tensile tests of
Ti-Al laminated composites (in 3, 5, and 7 bilayer configurations) were
performed at four various temperatures (25 ºC, 100 ºC, 200 ºC, and 300 ºC)
using strain rate of 0.017 /s. The effect of temperature, sonotrode travel direction,
and number of layers on the material behavior were discussed on the basis of
uniaxial tensile test results. The ultimate tensile strength and yield strength
is found to decrease with increasing temperature. In general, high strain
values were obtained in Y samples compared to X samples. The maximum strain
value was 0.42 at 300 °C temperature in the 5 bilayer Y sample.

RESUMO – Considerando que há relatos de possível intoxicação de milho por causa da dessecação de capim braquiária, o objetivo deste estudo foi determinar o melhor período para semear o milho ‘Yield Gard DKB 390 YC’ após a dessecação da cobertura. O delineamento experimental foi inteiramente casualizado, com quatro repetições. Os tratamentos consistiram em seis períodos de dessecação do capim ruziziensis (25, 20, 15, 10, 05 e 0 dias antes da semeadura do milho) e uma testemunha sem cobertura. As dessecações foram feitas em pleno florescimento do capim ruziziensis com glyphosate a 1,44 kg ha-1. Foram avaliadas as plantas de milho aos 30 e 50 dias após a semeadura (DAS) quanto à altura, área foliar, massa seca de folhas e caule. Aos 150 DAS, foi avaliada a altura de plantas e a inserção da espiga, diâmetro e comprimento da espiga, massa de 100 grãos e produtividade de grãos. A dessecação do capim ruziziensis no mesmo dia da semeadura do milho reduziu a altura das plantas, a altura de inserção da espiga, o diâmetro da espiga e a produtividade de grãos. A melhor época para a semeadura do milho ‘Yield Gard DKB 390 YC’ após a dessecação de capim ruziziensis com glyphosate foi aos 25 dias após a dessecação.Palavras-chaves: Brachiaria ruziziensis, Urochloa ruziziensis, cobertura vegetal, plantio direto, glyphosate. EFFECTS OF DESICCATION PERIODS OF RUZIZIENSIS GRASS ON GROWTH AND YIELD OF MAIZE ABSTRACT - Considering the possible occurrence of maize intoxication due to the desiccation of ruziziensis grass, the objective of this study was to evaluate the best period for sowing ‘Yield Gard DKB 390 YC’ in the no-tillage system. The experimental design was completely randomized with four replications. The treatments consisted of six periods of desiccation of ruziziensis grass (25, 20, 15, 10, 05 and 0 days before sowing maize) and one control without cover. The desiccations were done at full bloom of the ruziziensis grass with glyphosate at 1.44 kg ha-1. The maize plants were evaluated at 30 and 50 days after sowing (DAS) for height, leaf area, leaf and stem dry biomass. At 150 DAS, plant height and cob insertion, cob diameter and length, 100 grain mass and yield were evaluated. The desiccation of ruziziensis grass in the same day of maize sowing caused reduction in plant height, cob insertion height, cob diameter and yield. The best time for sowing ‘Yield Gard DKB 390 YC’ was 25 days after desiccation of ruziziensis grass with glyphosate.Keywords: Brachiaria ruziziensis, Urochloa ruziziensis, cover crop, no-tillage, glyphosate.

ABSTRACT - Understanding effects of climate variability over agricultural systems may support decisions to improve yield and environmental sustainability. Maize production systems in second season have a significant participation in Brazilian economy, and its yield depends of sowing times and soil water content. This work aimed to study maize yield in four sowing dates and supplementary irrigation in the second growing season in Brazil. The field experiment was developed in the 2015/2016 agricultural year in a completely randomized blocks design. Sowing dates were 01/27/2017, 02/09/2016, 02/25/2016 and 03/11/2016, and two irrigation conditions were adopted: the first without irrigation and the second with a supplementary irrigation of over 130% of the reference evapotranspiration (ET0). Yield performance indicated that the best result was obtained for the 01/27/2017 sowing date. The effects of supplementary irrigation affected the yield for the dates 02/25/2016 and 03/11/2016.Keywords: water balance, productivity, irrigation effect, Zea mays L. POTENCIAL PRODUTIVO DO MILHO PARA ÉPOCAS DE SEMEADURA EM SEGUNDA SAFRA SUBMETIDO À IRRIGAÇÃO SUPLEMENTAR RESUMO – O estudo dos efeitos da variabilidade climática na agricultura pode auxiliar nas tomadas de decisão para a melhoria contínua da produtividade e sustentabilidade ambiental. O milho de segunda safra no Brasil tem participação significativa na economia, e sua produtividade está vinculada, entre outros fatores, à pontualidade da semeadura e ao teor de água no solo. O objetivo deste estudo foi avaliar o efeito das épocas de semeadura em segunda safra no desempenho agronômico da cultura do milho em Tangará da Serra-MT, evidenciando a irrigação suplementar para semeaduras antecipadas, indicando a melhor época. O experimento foi realizado no ano agrícola de 2015/2016 com a cultivar de ciclo precoce AG 7088, em quatro épocas de semeadura (27/01/2016; 09/02/2016; 25/02/2016 e 11/03/2016), sob irrigação suplementar a 130% da evapotranspiração de referência (ET0) e sem irrigação, em delineamento experimental de blocos ao acaso com quatro repetições e parcelas de área útil de 7,2 m2. Foram avaliadas as características agronômicas para determinar o desempenho produtivo da cultura, em relação às épocas de semeadura em sistema irrigado e não irrigado. A semeadura realizada em 27/01 apresentou os melhores resultados de produtividade. A irrigação suplementar promoveu efeito sobre a produtividade nas épocas com restrição de chuvas (25/02/2016 e 11/03/2016).Palavras-chave: balanço hídrico, produtividade, efeito da irrigação, Zea mays L.

RESUMO - A colheita, sendo uma das principais etapas no processo produtivo, precisa manter as perdas dentro de um controle aceitável para que seja possível atingir o máximo nível de qualidade e produtividade. No presente estudo, objetivou-se avaliar as perdas quantitativas durante a colheita mecanizada do sorgo forrageiro por meio do controle estatístico de processo (CEP). O experimento foi arranjado em delineamento inteiramente casualizado (DIC), em que foi realizada a análise de variância para a verificação do efeito significativo da declividade e da velocidade operacional nas perdas, e, quando significativos, foi submetida ao teste de comparação de médias de Tukey a 5% de significância. Cartas sequenciais e cartas de controle para valores individuais e de amplitude móveis foram utilizadas como ferramentas de controle estatístico de processo para verificar o efeito da velocidade operacional nas perdas. Com base nos resultados obtidos é possível indicar que a faixa de velocidade operacional de 4 a 5 km h-1 apresentou a menor variação dos dados, não apresentando nenhum ponto fora do limite de controle, o que lhe conferiu a condição de faixa ideal para colheita. Com base na análise estatística houve maiores perdas no transporte à medida que se aumenta a faixa de declividade do terreno.Palavras-chave: colheita mecanizada, forragicultura, carta de controle, velocidade operacional. STATISTICAL PROCESS CONTROL (SPC) APPLIED IN THE MECHANIZED HARVEST OF SORGHUM ABSTRACT - Harvesting is one of the main steps in the production process and it is necessary to keep the losses under control in order to reach the maximum level of quality and productivity. The present study aimed to evaluate the quantitative losses during the mechanized harvesting of forage sorghum using the statistical process control (SPC). The experiment was arranged in a completely randomized design (DIC), and analysis of variance was performed to verify the significant effect of declivity and operational velocity on losses, and the significant was submitted to the Tukey test at 5% significance. Sequential charts and control charts for individual and mobile amplitude values, composed of upper and lower control and average limits, were used as statistical process control tools to verify the effect of operational speed on losses. Based on the results obtained it is possible to indicate that the operational velocity range from 4 to 5 km h-1 presented the lowest variation of data, presenting no point outside of the control limit, being the ideal range for harvest. The statistical analysis showed higher losses in transportation as the slope of the terrain increased.Keywords: Mechanized harvesting, forage farming, control charts, operational speeds.
