The overall carbothermic reduction to be studied is reaction (1).
Reaction (6) is reportedly difficult to happen[4], so it is hard to obtain the high active [Ti] during the process of the reduction reaction.
The first stage of the reaction is found to be the reduction of ilmenite forming elemental iron and TiO2 or other titanium oxides.
Conclusions This research has found that steel-bonded cemented carbide GT35 composites can be fabricated by carbothermic reduction of ilmenite.

Multivariate statistical analysis explains the huge and complicated current situation of the original data efficiently, concisely, and explicitly.
It simplifies the original data into representative factors, or bases on the similarity between data to cluster and identify clustering outcome.
This implies that high accuracy can be obtained when discriminant and cluster analyses are applied for data evaluation.
This study provided a novel thought of applying statistical diagnosis approach on anatomizing groundwater monitoring data.
Before subjecting to data processing, data selection and data standardization were the essential steps of data pre-processing.

The results for different datum precedence are summarized in this paper.
The functional tolerancing is now widely accepted by industry for contributing to a reduction of manufacturing costs while improving product quality [2].
However, the researches on the influences of datum precedence are still few.
If the datum precedence is plane | cylinder, the tolerance specifications for each part are specified with ISO tolerance language, as shown in Fig. 5.
While the datum precedence is changed, the final result is .

The process LCA-based water footprint method was applied using primary production data, with both volumetric and stress-weighted results reported.
Also, possible mitigation interventions for product supply chain water use impact reduction were raised on the basis of water footprint accounting.
Primary data were collected directly from the producer and supply chain stakeholders, which made this study different from other water footprint studies at product category level.
The authors have exercised complete freedom in designing the project, collecting and interpreting data and the decision to publish the results.

Vra�ar 2� 1Institute of Chemistry, Technology and Metallurgy, Department of Electrochemistry, Belgrade, Serbia and Montenegro 2Faculty of Technology and Metallurgy, University of Belgrade, Belgrade, Serbia and Montenegro Keywords: Enthalpy of Activation, Oxygen Reduction, Pt-Co Alloy, Reaction Mechanism ABSTRACT Oxygen reduction (OR) at a Pt3Co alloy electrode has been examined in alkaline solutions of different pHs in the temperature range from 274 to 313 K.
INTRODUCTION The oxygen reduction reaction is of most importance in electrochemical energy conversion devices such as fuel cells and metal-air batteries, as well as in corrosion and in several industrial processes.
In Fig. 2, the values of Tafel slopes, obtained from E - log j data in the high cd region, in solutions of different pHs, are plotted against T.
Analysis of the experimental data All the quantities on the right side of Eq. 11 are either known (El and Eh) or can be determined experimentally ( � � lEa,H , � � hEa,H and ( � F/T)[d ET / d (1/T)]).

Clustering analysis of high-dimensional data is one of the challenging issues in data mining.
Characteristics and Difficulties of High-dimensional Data Characteristics of High-dimensional Data.
(1) data sparsity: Due to the growth of data dimension, sparsity is data objects’ inherent characteristic in space distribution.
(4) effective dimension reduction methods: High-dimensional data clustering has an important characteristic, local feature selection that makes it different form traditional clustering.

Taken overall, the data suggest potential for the use of PLA in treating common wine faults, particularly ‘ladybug taint’, which is caused by elevated levels of IPMP.
Only data for IPMP and IBMP are reported here.
Measurement of lactic acid in the treated wines showed no change compared to control (data not shown), suggesting there was no degradation of PLA into its component lactic acid monomers.
Data represent the mean values of replicate treatments and measurements +/- SD.
Discussion and Summary This preliminary data demonstrates the capacity of PLA to decrease levels of these important taint compounds in red wine.
