Women Finding Their Voices in the Small Town Ministry Context: An Exploration of Values that Undergird Social Justice

grantor: Emmanuel CollegeThe concern of this thesis is with the formation of values for women who find themselves living in a small town in Central Ontario. For many years, I have questioned where our values come from. For example, does the church have any influence over the formation of our values? For people who are non-church members, what influences them? Do our values have anything to do with what we understand as spiritual experiences and social justice actions for our community? The idea for this thesis came to me over years as I observed the caring and compassion of many people in my community. Their selfless acts of generosity were noteworthy especially since many of the people I knew were not connected to my church community. At the same time, I myself was involved with the church and so knew many people there well. Sometimes, the same sense of compassion and generosity was not as evident amongst church people as I had experienced amongst non-church people. I became curious about this. My curiosity has led me to this research and my research question. Research Statement. It is my intention to explore the values which undergird commitment to social justice acts amongst church and non-church people. I wish to discover what kind of connection exists between an individual's spirituality, values and actions.D.Min

Analysis of pollutants found in municipal water and of those forming in the course of ozon disinfection

When the surface water to be treated contains bromides and ammonium salts, ozonation will stimulate the formation of bromates, nitrites and nitrates, which have been identified as potential cancerogenic species. The admissible concentration of nitrates defined in Polish Standards is 10 gN/m (which corresponds to ca. 44 gNO3/m3 ). In Germany, the admissible concentration of nitrites must not exceed 0.1 gN/m3 . In Poland, the admissible concentration ofbromates has not been established yet. The maximal admissible concentrations of bromates in drinking water recommended by US EPA and WHO range between 10 and 50mgBr03 /m3. Moreover, it is postulated that, in future, these levels should be decreased to 5 mg/m3 , as soon as appropriate methods have been developed to enable determination of such low bromate levels. The objective of the present study was to discuss the problems that have to be tackled when determining bromate and nitrate concentrations in municipal water by high-performance ion-exchange chromatograpliy (IC-HPLC) or other teclmiques. Our investigations fiave sliown that direct determinations of nitrates and bromates are feasible at concentrations of 2 gNO3/m3 and over 0.2 gBrO3/m3, respectively

Sorption of selected heavy metal ions on active carbons

Investigated was the sorption of heavy metals (Fe(III), Pb(II), Ni(II), Co(II) Cd(II) and Zn(II)) from aqueous solutions on carbon adsorbents which varied in surface properties. To examine the efficiency of single metal concentration on the carbon adsorbent use was made of the solid phase extraction technique. The initial carbon material was purchased from GRYFSKAND (Hajnówka, Poland). The adsorbents were processed by a variety physicochemical methods in order to change the porous structure, as well as the amount and type of the polar groups on the surface. Metal concentrations were measured by atomic absorption spectroscopy. Analysis of the sorption isotherms for heavy metals on modified active carbons suggests that the sorption process was affected by the type of the metal sorbed, by the pH of the solution, by the nature of the adsorbent surface and by the presence of other ions in aqueous solution

Adsorption of selected inorganic anions on active carbons

Carbon sorbents differing in surface properties were used for the adsorption of inorganic onions (Cl [-], Br [-], J [-], NO2 [-], NO3 [-], SCN [-], SO4 [2-], C2O4 [2-], CrO4 [2-]) from aqueous solutions. Making use of the solid phase extraction method, single onions, as well as a mixture of those, were investigated for the efficiency of concentration on the carbon sorbent. The initial carbon material (made of plum stones) was purchased from GRYFSKAND (Hajnówka, Poland). In order to change their porous structures, as well as the amount and type of the polar groups on their surfaces, the sorbents were processed by a variety of physicochemical methods. Anion concentrations were measured by ion chromatography and UV-VIS spectroscopy. Analysis of sorption isotherms for inorganic ions on modified active carbons suggests that sorption process was affected by the following factors: the type of the onion sorbed, the nature of the carbon sorbent surface, and the presence of other ions in the solution under test

Capillary action liquid chromatography (caLC) – Comparison of the retention parameters with data obtained using TLC

W artykule przedstawiono nową technikę chromatograficzną, kapilarną chromatografię cieczową (caLC), i możliwość jej zastosowania do analizy mieszaniny barwników spożywczych. Porównano chromatogramy uzyskane na płytkach do chromatografii cienkowarstwowej (TLC) oraz w kolumienkach kapilarnych (caLC). Zastosowano odwrócony układ faz, gdzie adsorbentem był modyfikowany żel krzemionkowy RP-8, a eluentem mieszanina: metanol-woda-kwas octowy (4:5:1, v/v). Porównano dane retencyjne uzyskane na płytkach TLC i w kapilarach caLC na różnych drogach rozwijania oraz w kapilarach o różnych średnicach i różnymi sposobami rozwijania chromatogramów (metodą wstępującą i zstępującą oraz horyzontalną).This article presents a new chromatographic technique, capillary action liquid chromatography (caLC) and a possibility of its application in the analysis of mixture of food dyes. This work compares chromatograms obtained on a plate of the thin layer chromatography (TLC) and in capillary columns (caLC). The reversed phases chromatography were applied, where modified silicate gel RP-8 was a sorbent, and eluent was a mixture: methanol-water-acetic acid (4:5:1, v/v). The paper compares the retention data obtained with capillary caLC and with TLC plates in various distance of development, additionally for analysis in capillaries with various inner diameters, and different modes of development (ascending, descending, horizontal)

Adsorpcyjne usuwanie wodnej fazy fioletu krystalicznego z wody za pomocą taniego aktywowanego węgla uzyskanego z martwych liści Palmy daktylowej (L)

Up to now, water pollution is still one of the important issues and challenges worldwide, due to its environmental, economic and human life impacts. It is also remains a challenge to environment scientists and technologists. Nowadays, the textile dyeing industry is considered one of the largest water consuming industries and produces large volumes of colored wastewater in its dyeing and finishing process. In this study, date palm tree leaflets (DPL) has been selected as a natural renewable source for the production of a new activated carbon (AC) utilized for the removal of crystal violet (CV) from water-dye system using a batch mode technique. The experiments studies were carried out at different initial dye concentration, contact time, adsorbent dose, and pH. The sorption exhibited high efficiency for CV adsorption and the equilibrium state could be achieved in 30 minutes for the different CV initial concentrations. CV removal was proved to increase with the increase in ACDL dose, pH, and contact time. Agitation rate and total volume of the reaction mixture were kept at 200 rpm and 20 mL respectively. The applicability of Langmuir and Freundlich isotherm equations was investigated and it was found that experimental data fitted very well to both Freundlich and Langmuir models. The maximum adsorption capacity (qm) was found to be 36.63 mg/g.Poziom zanieczyszczenia wody jest jednym z najważniejszych problemów do rozwiązania i wyzwań dla technologii remediacyjnych. Także przemysł farbiarski ma wpływ na zanieczyszczenie wód powierzchniowych ze względu na wytwarzanie dużych ilości ścieków powstałych w procesie barwienia i wykańczania materiałów. Liście palmy daktylowej zostały wybrane jako naturalne, odnawialne źródło materiału organicznego do wytwarzania węgla aktywnego, który może być wykorzystany w procesie usuwania fioletu krystalicznego. W trakcie badań zbadano wpływ stężenia barwnika, czasu kontaktu, masy złoża węgla aktywnego oraz pH wody na efektywność procesu usuwania barwnika. Na podstawie uzyskanych wyników można stwierdzić, że izotermy Freundlicha i Langmuira dobrze opisują przebieg procesu adsorpcji fioletu krystalicznego na złożu węgla aktywnego uzyskanego z martwych liści palmy daktylowej

Analiza substancji biologicznie aktywnych

W pracy opisano wykorzystanie barwy rozdzielanych substancji w analizie chemicznej, wykonywanej metoda chromatografii cienkowarstwowej TLC. Analiza substancji metodą TLC jest stosunkowo prosta i nie wymaga skomplikowanej aparatury, natomiast jej słabą stroną jest detekcja i identyfikacja rozdzielonych substancji. W związku z powyższym autorzy pracy zwrócili szczególną uwagę na metody detekcji substancji na płytkach chromatograficznych, zwłaszcza na różnego rodzaju reakcje z rozdzielonymi, bezbarwnymi substancjami, które zarówno umożliwiają ich wykrycie, jak i możliwość identyfikacji (analizę jakościową) na podstawie ich charakterystycznej barwy. Z drugiej strony intensywność zabarwienia otrzymanych pasm chromatograficznych na płytkach TLC maja bezpośredni związek z czułością i oznaczalnością tych substancji, gdyż im bardziej intensywną barwę posiada plamka rozdzielanej substancji, tym intensywnej absorbuje kwanty promieniowania UV-VIS a tym samym umożliwia detekcje tych składników na niższym poziomie stężeń
