FINANCIAL FEASIBILITY OF HOUSING INVESTMENT TYPE 36 IN THE CITY OF PALANGKA RAYA

The test results are the basis for analyzing whether housing construction type 36 was feasible. Analysis was carried out by the buyer's interest and determination. Likert’s scale analysis of financial feasibility is already done by using the criteria of Coast Benefit Ratio (BCR), Internal Rate of Return (IRR) and Break Event Point (BEP). Results of the research showed that buyers of Civil Servants very interested to have 36 types of homes in the city of Palangkaraya thus research was proceeding to the stage of financial analysts. The economic analysis of alternative cash flow techniques 1 (8 units), IRR = 28%> 11% (MARR), BCR = 1.05> 1, and BEP = 5. Cash flow alternative 1 (16 units) was IRR = 41,5 %> 11% (MARR), BCR = 1.08> 1, and BEP = 9 unit. Alternative cash flow 1 (24 units) was the value of IRR = 47.9%> 11% (MARR), BCR = 1.10> 1, and BEP = 7 units. Alternative cash flow 1 (32 units) was the value of IRR = 50.0%> 11% (MARR), BCR = 1.11> 1, and BEP = 7 units. Then the alternative cash flow 1 for feasible overall is based on the financial aspects. Cash flow analysis of alternative 2, and 3 have the same alternative, for the sale of 8 units acquired IRR = 12.3%> 11% (MARR), the value of BCR = 1.01>, and BEP = 8 units. Sales of 16 units acquired IRR = 14.9%> 11% (MARR), the value of BCR = 1.03> 1, and BEP = 16. For the sale of 24 units acquired IRR = 14.9%> 11% (MARR), the value of BCR = 1.03> 1, and BEP = 24 units, and for the sale of 32 units acquired IRR = 15.2%> 11% (MARR), the value of BCR = 1.03> 1, and BEP = 32 units. It is that the overall cash flow analysis of alternatives 2 and 3 were a feasible alternative based on the financial aspects. The economic analysis of alternative cash flow techniques 4 (8 units), IRR = 9.8% <11% (MARR), BCR = 0.99 < 1, which concluded that the alternative cash flow 4 (8 units) was not feasible based on financial aspects. Alternative cash flow 4 (16 units) is for value of IRR = 11.4%> 11% (MARR), BCR = 1.00> 1, and BEP = 16 units. Alternative cash flow 4 (24 units) is for the value of IRR = 11.7%> 11% (MARR), BCR = 1.01> 1, and BEP = 24 units. Alternative cash flow 4 (32 units) is for the value of IRR = 12.0%> 11% (MARR), BCR = 1.01> 1, and BEP = 32 units. So the alternative cash flow 4 with sales of 16 units, 24 units and 32 units for overall are feasible based on the financial aspects

An agent-based model to rural-urban migration analysis

In this paper we analyze the rural-urban migration phenomena as it is usually observed in economies which are in the early stages of industrialization. The analysis is conducted by means of a statistical mechanics approach which builds a computational agent-based model. Agents are placed on a lattice and the connections among them are described via an Ising like model. Simulations on this computational model show some emergent properties that are common in developing economies, such as a transitional dynamics characterized by continuous growth of urban population, followed by the equalization of expected wages between rural and urban sectors (Harris-Todaro equilibrium condition), urban concentration and increasing of per capita income.Comment: 16 pages, 9 figure

Incidencia del material cementante (cemento-cal) en el retemplado de un mortero hidráulico.

ilustraciones, diagramas, tablasEl retemplado consiste en adicionar agua para recuperar la consistencia de la mezcla antes de iniciar su fraguado. El agua adicionada por retemplado es función del agua perdida por evaporación antes del fraguado inicial, y su relación varía según la dosificación del material cementante. El objetivo de la investigación fue identificar cómo incide la dosificación del material cementante (cal/cemento) sobre el retemplado de un mortero hidráulico. Para conseguirlo, fue necesario, en distintos tiempos de retemplado, encontrar la cantidad de agua que recuperaba la consistencia de la mezcla, así como su relación con el agua evaporada, al cambiar la proporción de cal en el material cementante. En consecuencia, se prepararon morteros con tres proporciones de cal en relación al material cementante: 5%, 10% y 25%. Se evaluaron tres tiempos de retemplado: 1,5 horas, 2,5 horas, y 3,5 horas. A su vez, se consideraron dos condiciones de evaporación en cada tiempo de retemplado: media (CE1) y alta (CE2). Los morteros se fabricaron para una consistencia especificada: fluidez de 110%. Se concluyó que en condiciones similares de evaporación, la proporción del material cementante incide sobre el retemplado de la siguiente manera: al incrementar el contenido de cal de 5% a 10% se necesitó adicionar mayor cantidad de agua para recuperar la fluidez inicial de 110%, pero al seguir aumentando la cal hasta el 25%, la tendencia se invirtió, reflejando el efecto de la retención de agua producida por la cal sobre la evaporación; este comportamiento se observó en todos los tiempos de retemplado. Los resultados encontrados proponen una posible relación entre la velocidad de evaporación y el contenido de cal en el material cementante. (Texto tomado de la fuente)The retempering consists in adding water to recover the consistency of the mixture before it starts setting. The water added by retempering is a function of the water lost to evaporation before the initial setting, and its ratio varies depending on the dosage of the cementing material. The aim of the research was to identify how this affects the dosage of cementitious material (lime / cement) on retempering a hydraulic mortar. To achieve this, it was necessary, in different periods of retempering, to find the amount of water recovered by the consistency of the mixture, as well as the relationship with the evaporated water, when changing the proportion of lime in the cementitious material. Consequently, mortars were prepared with three proportions of lime relative to cementitious material: 5%, 10% and 25%. Three periods of retempering were evaluated, 1,5 hours, 2,5 hours, and 3,5 hours. In addition two conditions of evaporation were considered in each period of retempering: medium (EC1) and high (CE2). The mortars were made to a specified consistency: fluidity of 110%. It was concluded that under similar conditions of evaporation, the proportion of cementitious material affects the retempering as follows: when increasing the lime content from 5% to 10% more water was needed to recover the initial fluidity of 110%, but in further increasing the lime content to 25%, the trend was reversed; this behavior was observed in all the periods of retempering. The results suggest a possible relationship between the evaporation rate and the lime content in the cementitious materialLínea de Investigación: TecnologíaMaestríaMagíster en ConstrucciónÁrea Curricular Construcción y Hábita

Rural-urban migration in d-dimensional lattices

The rural-urban migration phenomenon is analyzed by using an agent-based computational model. Agents are placed on lattices which dimensions varying from d=2 up to d=7. The localization of the agents in the lattice define their social neighborhood (rural or urban) not being related to their spatial distribution. The effect of the dimension of lattice is studied by analyzing the variation of the main parameters that characterizes the migratory process. The dynamics displays strong effects even for around one million of sites, in higher dimensions (d=6, 7).Comment: 9 pages, 7 figures, to be published in International Journal of Modern Physics C 1

Fenologia e produção de cultivares de amoreira-preta em sistema agroecológico.

A amoreira-preta é uma espécie de exploração recente no Brasil. Nos últimos ano, s tem sido dada especial atenção ao cultivo orgânico ou agroecológico dessa espécie. O objetivo deste trabalho foi verificar o comportamento fenológico e produtivo das cultivares de amora-preta ‘Tupy’, ‘Guarani’, ‘Caingangue’, ‘Cherokee’ e ‘Brazos’, e das seleções denominadas ‘seleção 97’ e ‘seleção 787’ na região de Pelotas, Rio Grande do Sul(RS), em sistema agroecológico. O trabalho foi realizado na Estação Experimental de Cascata (EEC), Embrapa Clima Temperado. As plantas foram dispostas no pomar, em blocos varietais aleatórios, com 10 plantas por genótipo, perfazendo quatro linhas com duas cultivares por linha. Foram observadas as datas de início da floração e fim da floração, início e final de colheita, massa (gramas) e número de frutos por planta, teor de sólidos solúveis totais (ºBrix), produção média por planta (g pl-1) e produtividade estimada por hectare (kg ha-1). Para análise das características dos frutos, a média de cada ano de avaliação (três) foi considerada como uma repetição. Na região de Pelotas-RS, é viável o cultivo agroecológico de amoreira-preta. Não há diferenças de produção, produtividade, número de frutos e teores de sólidos solúveis totais entre os genótipos estudados
