Rocks correlated with the Hough Lake and Quirke Lake Groups of the Huronian Supergroup form part of a northeasterly trending corridor that separates 1750 Ma granitic intrusive rocks of the Chief Lake batholith from the 1850 Ma mafic intrusive rocks of the Sudbury Igneous Complex. This corridor is dissected by two major structural features; the Murray Fault Zone (MFZ) and the Long Lake Fault (LLF). Detailed structural mapping and microstructural analysis indicates that the LLF, which has juxtaposed Huronian rocks of different deformation style and metamorphism grade, was a more significant plane of dislocation than the MFZ. The sense of displacement along the LLF is high angle reverse in which rocks to the southeast have been raised relative to those in the northwest. South of the LLF Huronian rocks underwent ductile defonnation at amphibolite facies conditions. The strain was constrictional, defined by a triaxial strain ellipsoid in which X > Y > z. Calculations of a regional k value were approximately 1.3. Penetrative ductile defonnation resulted in the development of a preferred crystallographic orientation in quartz as well as the elongation of quartz grains to fonn a regional southeast-northwest trending, subvertical lineation. Similar lithologies north of the LLF underwent dominantly brittle deformation under greenschist facies conditions. Deformation north of the LLF is characterized by the thrusting of structural blocks to form angular discordances in bedding orientation which were previously interpreted as folds. Ductile deformation occurred between 1750 and 1238 Ma and is correlated with a regional period of south over north reverse faulting that effected much of the southern Sudbury region. Post dating the reverse faulting event was a period of sedimentation as a conglomerate unit was deposited on vertically bedded Huronian rocks. Rocks in the study area were intruded by both mafic and felsic dykes. The 1238 Ma mafic dykes appear to have been offset during a period of dextral strike slip displacement along the major fault'). Indirect evidence indicates that this event occurred after the thrusting at 950 to 1100 Ma associated with the Grenvillian Orogeny.

This study examined the attitudes of South Korean teachers of English in Jeollanamdo toward Konglish, particularly in relation to English education. The literature search shows that Konglish is a typical local variety, evolved from the borrowing and redefining of English words that became part of everyday South Korean speech. Konglish is not unique in this regard. Japlish in Japan and Chinglish in China developed for similar reasons and display the distinctive characteristics of those languages. However, Konglish is usually defined as poor and incorrect. Teachers in the study expressed embarrassment, shyness, guilt, and anger about Konglish. On the other hand, they also valued it as something uniquely theirs. Teachers believed that students should not be taught that Konglish is bad English. However, students should be taught that it is poor or incorrect. With few exceptions, they correct Konglish in their classes. Teachers exhibited considerable inner conflict. They defined Konglish as valid when used in Korea with Koreans. However, some preferred that their students not use it, even with their friends. This may cause students to judge Konglish as unacceptable or inferior. The teachers believed that students should learn to distinguish between Konglish and "Standard English," and that they should learn about the contexts in which each is appropriate or preferred. The conclusion, therefore, is that South Korean teachers see the value of teaching about varieties of English. The recommendations are that intelligibility, broader communication skills, and information about International English be included in the curriculum in South Korea.

Arsenic, bismuth, germanium, antimony and tin were simultaneously determined by continuous hydride generation and inductively coupled plasma-atomic emission spectrometry . I Hydrides were introduced into four different types of gas-liquid separators. Two of the gas-liquid separators were available in-house. A third was developed for this project and a fourth was based on a design used by CET AC. The best signal intensity was achieved by the type II frit-based gas-liquid separator, but the modified Cetac design gave promise for the future, due to low relative standard deviation. A method was developed for the determination of arsenic, bismuth, antimony and tin in low-alloy steels. Four standard reference materials from NIST were dissolved in 10 mL aqua regia without heat. Good agreement was obtained between experimental values and certified values for arsenic, bismuth, antimony and tin. The method was developed to provide the analyst with the opportunity to determine the analytes by using simple aqueous standards to prepare calibration lines. Within the limits of the samples analyzed, the method developed is independent of matrix.

The capability of molecular mechanics for modeling the wide distribution of bond angles and bond lengths characteristic of coordination complexes was investigatecl. This was the preliminary step for future modeling of solvent extraction. Several tin-phosphine oxide COrnI)le:){es were selected as the test groUl) for t.he d,esired range of geometry they eX!libi ted as \-vell as the ligands they cOD.tained r Wllich were c\f interest in connection with solvation. A variety of adjustments were made to Allinger's M:M2 force·-field ill order to inl.prove its performance in the treatment of these systems. A set of u,nique force constants was introduced for' those terms representing the metal ligand bond lengths, bond angles, and, torsion angles. These were significantly smaller than trad.itionallY used. with organic compounds. The ~1orse poteIlt.ial energ'Y function was incorporated for the M-X l')ond lE~ngths and the cosine harmonic potential erlerg-y function was invoked for the MOP bond angle. These functions were found to accomodate the wide distribution of observed values better than the traditional harmonic approximations~ Crystal packing influences on the MOP angle were explored thr"ollgh ttle inclusion of the isolated molecule withil1 a shell cc)ntaini11g tl1e nearest neigl1'bors duri.rlg energy rninimization experiments~ This was found to further improve the fit of the MOP angle.

A system comprised of a Bomem interferometer and a LT3-110 Heli-Tran cryostat was set up to measure the reflectance of materials in the mid-infrared spectral region. Several tests were conducted to ensure the consistency and reliability of the system. Silicon and Chromium, two materials with well known optical properties were measured to test the accuracy of the system, and the results were found to be in good agreement with the literature. Reflectance measurements on pure SnTe and several Pb and Mn-doped alloys were carried out. These materials were chosen because they exhibit a strong plasma edge in the mid infrared region. The optical conductivity and several related optical parameters were calculated from the measured reflectance. Very low temperature measurements were carried out in the far-infrared on Sn9SMn2Te, and the results are indicative of a spin glass phase at 0.8 K. Resistivity measurements were made at room temperature. The resistivity values were found, as expected, to decrease with increasing carrier concentration and to increase with increasing manganese concentration.

The bill is a proposal by the government to purchase Welland Canal stock held in private hands. The bill was read for the first time on Wednesday 4 August, 1841, and received second reading on 10th August, 1841. One hundred and fifty copies were printed of the bill. This example was addressed to Samuel Street at the Falls of Niagara, by William Hamilton Merritt, September 1841.

These are the annual proceedings of the Grand Lodge A.F. & A.M. of Canada in the Province of Ontario covering a single year of activity. The entire collection of proceedings cover the years 1855 to 2010. Future proceedings will be added to the website. Freemasonry is the oldest and largest worldwide fraternity dedicated to the Brotherhood of Man under the Fatherhood of a Supreme Being. In Ontario, the governing body is called the Grand Lodge of Ancient Free and Accepted Masons of Canada in the Province of Ontario. It is under the leadership of the Grand Master. He presides over the 53,000 Masons who belong to one or more of the 571 lodges in his jurisdiction.
