Interesting Area

Iron as One of primary raw material in steel and construction industry, it's presence and potencies in Indonesia have an important role. Genetically, known 3 formation of iron deposits (1) Primary, (2) Lateritic, (3) Secondary/reworking process.Based on the survey conducted in Ende in 2005, the typical of iron deposits in this area is classified into sedimentary iron deposits (due to leaching, transporting, accumulating and depositing in somewhere). The accumulation of magnetite grains suggested is due to by leaching, washing in the long term and occurs intensively, so that produce high magnetite concentration in certain area. The interesting area is spread in four sectors; Rapo Rindu, Bheramari, Ruku Ramba and Ondorea sectors.The result of physical laboratory analysis (in concentrate) show the magnetite degree (MD) is vary from 10% to 50%, whereas from chemical analysis known the highest grade reach 37.10% and lowest grade is around 4.4%. However, the everage grade, in general are from 10 to 25 %.The potential of the deposits is obtained from combination between field work laboratory analysis and for those areas mentioned above the total hypothetics resources is 57.134.358,4 ton (concntrate). It seem the deposits of this area is not economic in mining view because very small (under 100 millions tonnes).

Two Factors

The aim of laboratory analysis carried out on pottery fragments recovered from the Poienești-Lucaşeuca (PL) site of Orheiul Vechi and the Getic site of Butuceni was to verify the hypothesis that there was a continuity in pottery technology traditions and the hypothesis that there was continuity in raw material use. In order to verify these hypotheses, i.e. to determine whether we are dealing with continuity or with changes in pottery manufacturing, two factors must be taken into account: know-how and raw material. This means that it is necessary to perform both technological and raw material analyses. For the purposes of this study the following methods were used: MGR-analysis, chemical analysis by WD-XRF, thin-section studies and an estimation of physical ceramic properties. The results of archaeometric analysis of pottery from the PL site of Orheiul Vechi and the Getic site of Butuceni did not substantiate the hypothesis that there had been a continuity in pottery technology traditions. The results of archaeometric analysis of pottery from the PL site of Orheiul Vechi and the Getic site of Butuceni did, conversely, confirm the hypothesis that there was a continuity in raw material use. At both sites and in both phases there is a marked emphasis on local production of ceramics using locally sourced raw materials.

Granite Samples

The Montorfano and Baveno granite ore bodies are located in the Lake District (VCO-NE Piedmont). They were and are still quarried as dimension stones, with a consequent production of a huge volume of “waste.” In 1995, an Italian company (GMM S.p.A) decided to invest in the valorisation of granite quarry waste as a secondary raw material. An in situ geological prospecting was carried out in order to evaluate the characteristics of the material and the thickness and volume of the useful disposal sites that could be used (by means of geophysical surveys). As a consequence of the field work, the amount of quarry waste was estimated as nearly 2 Mm3. Chemical analysis was carried out on 75 granite samples, in order to individuate the Fe2O3 grade: from 1.321–2.593% of the original waste to 0.160–0.228% after the “dry process” treatment. Three different detailed maps that show the typology, the locations, and the quality distribution of the material in the dumping areas have been drawn up.

The Naskapi Nation of Kawawachikamach is an Aboriginal community located in northern Quebec near the Labrador Border. Given the region’s rich iron deposits, the Naskapi Nation has considerable experience with major mineral development, first in the 1950s to the 1980s, and again in the past decade as companies implement plans for further extraction. This has raised concerns regarding a range of environmental and socio-economic impacts that may be caused by renewed development. These concerns have led to an interest among the Naskapi to develop a means to track community well-being over time using indicators of their own design. Exemplifying community-engaged research, this paper describes the beginning development of such a tool in fall 2012—the creation of a baseline of community well-being against which mining-induced change can be identified. Its development owes much to the remarkable and sustained contribution of many key members of the Naskapi Nation. If on-going surveying is completed based on the chosen indicators, the Nation will be better positioned to recognize shifts in its well-being and to communicate these shifts to its partners. In addition, long-term monitoring will allow the Naskapi Nation to contribute to more universal understanding of the impacts of mining for Indigenous peoples.

Antiaggregant Therapy

The article presents the results of a study to assess the functional reserve of the kidneys against the background of a comparative study of antiaggregant therapy dipyridamole and allthrombosepin in 50 patients with a relatively early stage of chronic kidney disease. Studies have shown that long-term administration of allthrombosepin to patients has resulted in better maintenance of kidney functional reserves. Therefore, our research has once again confirmed that diphtheridamol, which is widely used as an antiaggregant drug in chronic kidney disease, does not lag behind the domestic raw material allthrombosepin

Diabetes mellitus is a metabolic syndrome that causes impairment, mortality, and many other complications. Insulin and several synthetic medications are currently used in the treatment of diabetes. However, these pharmaceutical drugs are costly, and therefore medicines place priority on alternatives to fight this lethal disease. This modest study aims to investigate the chemical composition, antidiabetic and antihyperglycemic potentials along with subacute toxicity (bodyweight change and biochemical parameters) of hydroethanol extract from Withania frutescens L. roots (WFRE). The chemical analysis was carried out using GC–MS after extract silylation. The chemical analysis identified many potentially active compounds that may determine the antidiabetic results of WFRE. The antidiabetic effect of WFRE was evaluated in mice with severe diabetes using oral administration of doses up to 400 mg/kg for 28 days. The results of the antidiabetic and antihyperglycemic tests indicate that WFRE possesses promising glucose-lowering effects and, as a result, it may serve as an antidiabetic alternative for long-term use. The 4-week treatments with different doses of plant extract did not alter the bodyweight appearance of the diabetic mice nor their biochemical parameters (AST and ALT). The findings obtained indicate that the studied plant extract controlled severe diabetes in mice. Therefore, Withania frutescens L. can serve society as it provides natural agents to control diabetes.

I have the great pleasure to be the citationist for presentation of the 1992 Paleontological Society Medal to Dr. Malcolm C. McKenna. Malcolm McKenna has had a profound influence on our profession, both as a research scientist and a mentor. He is one of the most broadly trained and interested scientists I know, and he has a consuming passion for learning. He loves all aspects of paleontology—field work, literature, laboratory analysis of specimens, theory, even fossil preparation (in his enthusiasm to uncover critical specimens, or trusting only himself to perform delicate preparation of unique fossils). Malcolm has never been afraid to propose controversial ideas, to change his mind when wrong, to tackle problems that others consider insoluble, or to incorporate new scientific techniques in his work before others realize their significance.

Concrete is the most versatile, durable and reliable material and is the most used building material. It requires large amounts of Portland cement which has environmental problems associated with its production. Hence, an alternative concrete – geopolymer concrete is needed. The general aim of this book is to make significant contributions in understanding and deciphering the mechanisms of the realization of the alkali-activated fly ash-based geopolymer concrete and, at the same time, to present the main characteristics of the materials, components, as well as the influence that they have on the performance of the mechanical properties of the concrete. The book deals with in-depth research of the potential recovery of fly ash and using it as a raw material for the development of new construction materials, offering sustainable solutions to the construction industry.

This paper shows how a long term process of narrative inquiry may act as a reflective tool for challenging and revising preliminary researcher frames for an inquiry. In this paper I return to a detailed set of fieldnotes taken over a several year period to show how my own assumptions and biases changed throughout the course of inquiry. This work is based on a study of newcomer Chinese family educational narratives. Several stories encountered during the first days of field work are revisited as they show up through the course of conducting field work.

This autoethnographic essay is focused on methodological space of “problematization”—the wrenching intellectual and emotional process (and lived experience) that a scholar goes through before settling into a long-term writing project—in this case travel to different parts of the world, in an attempt to explore the idea and experience of “Peace” in each of those places. Weaving through elements of family memoir, Georgia history, eco-criticism, and Peace Studies (across different sub fields), the essay illuminates the personal and liminal space of methodological engagement before field work.
