Abstract:

Considering the importance of cassava starch for Brazilian industries, the current work aimed at evaluating the effects of extrusion parameters on the physical characteristics, mainly viscosity properties of extruded cassava starch. A factorial central composite design (2³) with three independent variables and the response surface methodology were used to evaluate the results of expansion index, specific volume, water absorption index, water solubility index, color and paste properties, according to the variations in the moisture content, barrel temperature and screw speed. Results indicated t

Abstract:

The Turkey Lakes Watershed (TLW) in central Ontario was selected for intensive research into the effects of the long-range transport of air pollutants (primarily acidic deposition) at a site on the Canadian Shield having both vulnerable terrain and an undisturbed Great Lakes forest type. The terrestrial and aquatic resources within the basin are representative of the surrounding region of Algoma, although for Ontario, it does have high relief (290 m) and high annual precipitation (>1200 mm). The TLW contains a chain of four lakes (five distinct lake basins) that range from 5.8 to 52.0 ha in

Abstract:

The main controlling factor in oxygen converting with top blowing is the stream of oxygen, which penetrate the metal bath and promotes the flow of heat, mass exchange and chemical processes. The inherent characteristics of the oxygen jet are created by the nozzle tip with nozzles that may differ in design depending on the issue they solve. In the electrometallurgical industry, coherent nozzles consisting of a central nozzle for supplying the main oxygen jet and a surrounding annular nozzle for supplying shielding gas, mainly methane, are used to ensure deep penetration of the oxygen jet

Abstract. Knowledge about potential operators, about the preconditions of their applicability, and about their effects is essential to interact effectively with the physical world. Four classes of representational units of this knowledge can be distinguished: I) rules, II) structures, III) instances, and IV) episodes. Two important characteristics of these units are the abstractness of content and the directionality of access. A multinomial model is presented that enables the measurement of these characteristics.

Vela Supernova remnant (SNR) is one of the nearest SNRs to Earth and serves as a space laboratory of relativistic and pulsar astrophysics. In particular, its synchrotron radio emission is determined by physical processes both in the remnant and in pulsar wind nebula (PWN), that resides in central part of remnant. In our work we separate the total radio flux from Vela SNR on fluxes from remnant and from PWN. It is shown that flux from the remnant is detected in MHz- range and is generated in the whole volume of remnant with uniform emissivity, while as flux from PWN is detected in MHz-GHz range

Kampung Kauman in Surakarta, Malang, and Pekalongan are selected as part of the similar cities with its dynamics and development. This background of the formation of them has also become one of the considerations. The methodology was a case study, which researchers

Abstract:

The assessment of the micromorphological characteristics of soils is a powerful tool for studying the transformation of soils under the influence of various weathering mechanisms (physical, biogenic). The central part of Yakutia is characterized by a large area of agricultural lands, some of which has become fallow land and is subject to cryogenic processes, fires and anthropogenic impact. Under the conditions of climate change, the fallow soils of Yakutia can be re-involved in the agricultural complex. To study their state, a method of micromorphological investigation of thin soil sections is

Abstract Biological invasion as one of the main threats to natural ecosystems has big economic impact on conservation of nature. Studies of the population biology of invasive species may allow more precise focus on specific plant and soil characteristics involved in invasiveness. The aim of the study was to investigate the relationship between selected biological population characteristics of Impatiens parviflora and a few chosen chemical and physical soil features. Sites were selected because of the poor mapping of invasive plants in the protected natural areas and their interactions with spe

Abstract:

Watershed conditions in Indonesia have been degraded over time, which is marked by increasing area of critical land. The vast area of critical land was evidenced to be a serious threat for watershed carrying capacity which eventually affected the hydrology imbalance in the watershed area. One among watershed with degraded lands which seriously requires priority handling is Comal watershed. The purpose of this study is to identify the physical characteristics of Comal watershed which have significant influence in determining the runoff and calculating the runoff coefficient by taking into accou

Rattan in good quality is curently difficult to obtain and it price is quite expensive. So, it is needed to utilize non commercial rattan as substitute material. By identification of basic characteristics , such as phisical, mechanical, chemical and anatomy structure, every species of non commercial rattan can be used appropriately. The objectives of this research is to optimize utilization non commercial rattan as subtitute material and develop rattan manufacturing industry especially by identivication of the physical and mechanical characteristics.

Abstract:

Continuous urbanization and industrialization lead to plenty of rural residents migrating to cities for a living, which seriously accelerated the population hollowing issues. This generated series of social issues, including residential estate idle and numerous vigorous laborers migrating from undeveloped rural areas to wealthy cities and towns. Quantitatively determining the population hollowing characteristic is the priority task of realizing rural revitalization. However, the traditional field investigation methods have obvious deficiencies in describing socio-economic phenomena, especially

The purpose of the research was to assess the relationships between socioeconomic status, cycle length, duration of menses, regularity and dysmenorrhea. A survey was conducted among 896 healthy women from Łódź and Warsaw (Poland), aged 15.71–26.98. Women who were menarche at least 3 years ago were asked to complete the survey. Women were asked about cycle length (number of days), duration of menstrual flow, regularity of the cycle, dysmenorrhea, birth place, parental education level, atten

We have studied and compared kinematic characteristics of the motion of coronal mass ejections (CMEs) in three-dimensional (3D) space for three groups of CMEs for the period 2008–2014. These CME groups include: (i) stealth CMEs, (ii) CMEs that originate on the visible side of the Sun (for an observer on Earth) and are associated with X-ray flares and filament eruption, (iii) all CMEs registered during the given period. Stealth CMEs are CMEs that emerge on the visible side of the Sun and are unrelated to X-ray flares, as well as to filament eruption. We compare kinematic and some physical chara

Abstract - Laser-Induced Breakdown Spectroscopy (LIBS) is one method of atomic emission spectroscopy using laser ablation as an energy source. This method is used to characterize the type of amethysts that originally come from Sukamara, Central Kalimantan. The result of amethyst characterization can be used as a reference for claiming the natural wealth of the amethyst. The amethyst samples are directly taken from the amethyst mining field in the District Gem Amethyst and consist of four color variations: white, black, yellow, and purple. These samples were analyzed by LIBS, using laser energy
