A Zona da Mata Mineira foi alvo do intenso cultivo de café, contribuindo para redução, e consequente fragmentação, da Mata Atlântica na Região. A Universidade Federal de Viçosa (UFV) possui, em seu Campus sede situado na cidade de Viçosa/MG, fragmentos de vegetação de Mata Atlântica, que são importantes para a manutenção da flora e fauna locais. Sendo assim o presente trabalho teve como objetivo, num primeiro momento, propor adequações para as áreas de vegetação permanente, e, posteriormente, indicar corredores ecológicos interligando os fragmentos de vegetação de modo a garantir o fluxo gênico entre os remanescentes florestais dentro do Campus. Para isso foi utilizada uma imagem Ikonos do ano de 2007 do campus da universidade e por meio dela mapeou-se a hidrografia e também foi feita a classificação do uso do solo adotando como critério a interpretação visual. Em seguida, procedeu-se com a delimitação das áreas de preservação permanente de acordo com os critérios do Novo Código Florestal Brasileiro (Lei 12.651/2012). Como resultado, obteve-se a necessidade de se recuperar 54,68 ha de Áreas de Preservação Permanente (APP) para adequá-la a legislação vigente, assim como a criação de 9,58 ha de corredores ecológicos para a ligação entre os remanescentes florestais.Palavras-chave: área de preservação permanente, uso e ocupação do solo, Mata Atlântica.

O objetivo deste trabalho foi avaliar o efeito da pressão e do tempo de compactação nas propriedades de briquetes produzidos com resíduos de madeira laminada de paricá (Schizolobium amazonicum). Os resíduos provenientes da laminação de madeira foram coletados em empresas laminadoras, localizadas na região de Dom Eliseu, no estado do Pará. Os briquetes foram produzidos em uma briquetadeira laboratorial sendo testadas três pressões (1000, 1250, 1500 PSI) e três tempos de compactação (3, 5 e 7 minutos). Foram avaliadas: umidade de equilíbrio higroscópico, taxa de retorno no comprimento, taxa de retorno no diâmetro, carga de ruptura, densidade aparente, densidade energética e poder calorífico útil (PCU). Os resultados mostraram que a pressão e o tempo de compactação influenciaram significativamente as propriedades dos briquetes. A pressão de compactação do processo interferiu na densidade aparente e na densidade energética dos briquetes de forma semelhante, sendo as maiores médias encontradas para a maior pressão aplicada. O tempo de compactação teve menor influência nas propriedades dos briquetes. Concluiu-se que para obter uma maior produtividade, os briquetes de paricá devem ser produzidos com tempo de 3 minutos de compactação e pressão de 1500 PSI, o qual permitirá a geração de briquetes com propriedades adequadas para uso energético.Palavras-chave: densificação, bioenergia, Schizolobium amazonicum. EFFECT OF PRESSURE AND COMPRESSION TIME IN PROPERTIES OF PARICÁ WOOD WASTE BRIQUETTES ABSTRACTThis work aimed to evaluate the influence of pressure and compression time on the properties of briquettes prepared with paricá (Schizolobium amazonicum) veneer wood waste. The wood waste was collected in veneer companies, located in the region of Dom Eliseu, Pará. The briquettes were produced in a laboratory briquetter being tested three pressures (1000, 1250, 1500 PSI) and three times compression (3, 5, 7 minutes). Equilibrium moisture content, rate of return in length and diameter, tensile strength, apparent density, energy density and net calorific value were evaluated. The results indicated that pressure and compression time have influenced the properties of the briquettes. The compaction pressure interferes in the briquette apparent density and energetic density similarly, with higher averages found for the higher pressure. The time of compression had less influence on the properties briquettes. It was concluded that to achieve greater productivity, paricá briquettes must be produced with a time of 3 minutes and compression pressure of 1500 PSI, which will allow the generation of briquettes with properties suitable for energy use.Keywords: densification, bioenergy, Schizolobium amazonicum.

RESTRIÇÕES AO USO DA ESTUFA PARA DETERMINAÇÃO DE UMIDADE DE CASTANHA DO BRASILA castanheira-do-brasil (Bertholletia excelsa Bonpl.) é uma planta nativa da região da Amazônia. As nozes são amplamente utilizadas como alimento e nas indústrias de cosméticos. Durante o seu processamento, um dos parâmetros mais importantes para ser determinado é o teor de umidade, o qual é crítico para as etapas de secagem e armazenagem. Assim, o objetivo deste estudo foi verificar a exatidão do método de estufa a 105 °C por 24 h sobre a determinação de umidade para a castanha do Brasil, em comparação com os níveis de umidade determinados por titulação de Karl Fisher. Verificou-se que a aplicação da estufa a 105 °C por 24 h para determinar o teor de umidade da castanha não é eficiente, uma vez que os resultados foram mais elevados do que os obtidos a partir de titulação de Karl Fisher. As amostras submetidas à estufa apresentou alto índice de peróxidos, indicando a sua oxidação e consequente formação de compostos voláteis, que poderia ser a razão para a superestimação do teor de umidade determinado.Palavras-chave: Karl Fischer, óleo, peróxido, qualidade. ABSTRACTThe Brazil nut plant (Bertholletia excelsa Bonpl.) is native from Amazonia region. The nuts are extensively used as food and in cosmetic industries. During its processing, one of the most important parameters to be determined is its water content, which is critical to drying and storage steps. Thus, the objective on this study was to verify the accuracy of the method of oven at 105 °C to 24 h on water content measurement for Brazil nuts, in comparison to water content levels determined by Karl Fisher titration. It was verified that applying oven at 105 °C to 24 h to determine water content of Brazil nuts is not adequate, once the results were higher than those obtained from Karl Fisher titration. The samples submitted to oven showed high peroxide value, indicating its oxidation and consequent formation of volatile secondary compounds, which could be the reason to overestimation of water content determined.Keywords: Karl Fischer, oil, peroxide, quality.

Authors: Hayder Majeed Oleiwi  
Published: July 2024

Laboratory investigations were performed in order to assess the effectiveness of three types of inhibitors, calcium nitrite, ethanolamine and Sika ferro gard 901(commercial inhibitor) with 1%, 2% and 3%concentration by weight of cement for each inhibitor to retarding corrosion of steel embedded in concrete. Concrete specimens were used to assess the effects of corrosion inhibitors on the compressive and tensile strength of concrete and corrosion of reinforcement.Some of the specimens were subjected to wetting and drying cycles and reinforcement corrosion was evaluated by measuring corrosion potentials and corrosion current density. Other concrete specimens were immersed in the salt (Cl-+So3-2) solution and reinforcement corrosion was accelerated by impressing an anodic potential of +12 V from a DC power supply and measuring the time-to-cracking of the concrete specimens.The results indicated that the concrete specimens incorporated corrosion inhibitors of calcium nitrite and Sika ferro gard 901 did not adversely affect the compressive and tensile strength of concrete. Furthermore, the time-to-cracking in specimens contains those two inhibitors (calcium nitrite and Sika ferro gard 901) were higher. Two percent of calcium nitrite followed by three percent of Sika ferro gard 901 were efficient in delaying the initiation of reinforcement corrosion and reducing the rate of reinforcement corrosion current density in the concrete specimens, while all the percentages of ethanolamine corrosion inhibitor were ineffective to delay corrosion of the rebar under the conditions of the study and it's adversely affect the strength.

Authors: Al-Hmood Hussien 
Published: July 2024

In this paper, the performance of Energy Detection (ED) over K-M shadowed fading channel is investigated using the Moment Generating Function (MGF) of the received Signal-to-Noise Ratio (SNR). The K-M shadowed is a generic composite fading channel of K- M fading and which represents the impact of multipath in line-of sight (LoS) communication scenario and Nakagami - m distribution. The study is then extended to include Maximal Ratio Combining (MRC), Square Law Combining (SLC), and Square Law Selection (SLS) diversity receivers. The simulation and numerical results for the Complementary Receiver Operating Characteristics (CROC) and average Area under the CROC (CAUC) curves are given for different scenarios and compared with some previous works. These results show an improvement in the overall detection capability of ED is noticed when the diversity receptions are employed. In contrast to previous works which are limited by the values of the fading parameters, the proposed approach is not restricted by any condition.
A Numerical Investigation of the Effect of Increasing Blade Numbers on Cavitation and Performance of Centrifugal Pumps at Constant Parameters
Authors: Kareem Sakran Hayder 
Published: July 2024

In the present paper, a numerical study has been investigated by using computational fluid dynamics (CFD) to analyze pressure, head, head coefficient, pressure coefficient, input power, and volume fraction of cavitation at three cases of simulation in which each one has constant parameters; however, with modifying number of blades which is changed from five to sixteen. The constant parameters are rotating speed, volume flow rate, mass flow rate, outlet diameter, suction specific speed Nss, Reynolds number and NPSHr. These parameters have been fixed to have the same conditions for each case. The shear stress transport (SST) turbulence model has been used to inspect a steady state incompressible flow through centrifugal pump numerically. The simulation has done by using ANSYS®, Vista CPDTM Release 15.0. The results are plotted and discussed to describe and find a relation among cavitation, pump behavior, and variation of blade numbers at constant conditions. The results show a strong relation among increasing blade numbers, centrifugal pump performance and reducing pump cavitation.

Published: July 2024

Recently, the number of accidents in Iraq increases sharply after 2003 as the number of vehicles increases rapidly. The absence of adequate documentation system leads to unclear picture of the cause of these accidents. Therefore, this study tries to put the first step toward recoding the accurate details of the accidents. The GIS technique has been adopted as a knowledge base for the accidents recording along different types of roads within Al-Najaf city as study case. Reference points have been suggested on roads using electrical columns which already were installed along these roads. To link these referencing points together with GIS, there is a need for new accident form. This form will includes, in addition to the types of accidents, the causes of accidents and the name of roads, the referencing point which is close to the accident location. This system has been built according to field data collecting from miscellaneous resources. The developed model is able to indicate the black spot location (i.e. the location with high frequency of accidents) by change the color of points or segments relating to black spot. The developed system now is ready to be used by the authority of traffic.

Authors: Munjal Shikhil , Singh Gurcharan 
Published: July 2024

Earnings quality has emerged as an important phenomenon for many types of investors looking to invest in stocks. There are different approaches to determine the level of earnings management in academic research on earnings quality. To quantify earnings quality, the present study used the four techniques suggested by Penman (2001), Barton and Simko (2002), Leuz et al. (2003), and Desai et al. (2006). Using a sample of 65 companies from six major industries on the National Stock Exchange over a 12-year period, this study seeks to determine whether there is any consistency among the four measures of earnings quality. The analysis showed that a single approach cannot be used to define an organization as high or low quality. Hence, this study sheds light on the inconsistency of earnings quality measurements and advises firm stakeholders to employ several indicators when making decisions.
