Whit Oak Lake was listed on the 2008 Section 303(d) List if impaired waters in four categories. The first phase of the project has already helped to affect approximately 60% of the watershed. There has been an estimated sediment reduction of 609 tons per year with phase one. The structure being planned for the South end of the lake, (phase two) will affect nearly all of the remaining 40%. If we can accomplish similar results, we can expect a sediment reduction of approximately 273 tons additional per year. We have been working with the Mahaska County NRCS office, Snyder & Associates (engineers) and private landowners in the watershed to make this project a reality.

Landfill site from the National Priorities List (NPL). The EPA is inviting public comment on the proposed de-listing of the site from the NPL. The Iowa Department of Public Health in cooperation with the Agency for Toxic Substances and Disease Registry (ATSDR) prepared this health consultation to review the current status of the Red Oak Landfill site and to provide an evaluation of any public health consequences of de-listing the site. The information in this health consultation was current at the time of writing. Data that emerges later could alter this document’s conclusions and recommendations.

Two vegetable wastes, cork bark and grape stalks, were investigated for the removal of methylene blue from aqueous solution. The effects of contact time, dye concentration, pH, and temperature on sorption were studied relative to adsorption on a commercially-activated carbon. The highest adsorption yield was obtained within the pH range 5 to 10 for grape stalks and 7 to 10 for cork bark. The sorption kinetics of dye onto activated carbon and grape stalks was very fast. Kinetics data were fitted to the pseudo-first and second order kinetic equations, and the values of the pseudo-second-order initial rate constants were found to be 1.69 mg g-1 min-1 for activated carbon, 2.24 mg g-1 min-1 for grape stalks, and 0.90 mg g-1 min-1 for cork bark. Langmuir maximum sorption capacities for activated carbon, grape stalks, and cork bark for methylene blue estimated by the Orthogonal Distance Regression method (ODR) were 157.5 mg g-1, 105.6 mg g-1, and 30.52 mg g-1, respectively. FTIR spectra indicated that carboxylic groups and lignin play a significant role in the sorption of methylene blue. Electrostatic forces, n-p interactions, cation-p, and p-p stacking interactions contribute to methylene blue sorption onto grape stalks and cork bark. Grape stalks can be considered an efficient biosorbent and as a viable alternative to activated carbon and ion-exchange resins for the removal of methylene blue

Ilmavoimien ohjaajakursseilla on viime aikoina tapahtunut lisääntyvässä määrin lentopahoinvointeja, jotka saattavat johtaa lentopalveluksen keskeytykseen. Lisääntyneiden pahoinvointien ja pienentyneen hakijamäärän vuoksi on alettu tutkia mahdollista valintajärjestelmän kehittämistä lentopahoinvointiin taipumuksen testauksen osalta, koska jokainen tapahtunut keskeytys vähentää yhden henkilön jatkokoulutuksesta. Tutkimuksen pääongelma: - Onko korvan kaarikäytävän sakka lentopahoinvointia laukaiseva tekijä? Tutkimuksen alaongelmat: - Onko ruokailun ajankohdalla yhteyttä lentopahoinvointiin? - Ennustavatko valintatilaisuuden testit (esitiedot) lentopahoinvointia? - Onko lentointensiteetillä vaikutusta lentopahoinvoinnin esiintymiseen? Tutkimusaineistona ovat psykofysiologiset tilastot (v. 94-04), julkaistut teokset, aiemmat tutkimukset, aikakausilehdet sekä OAK:lta 78 ja 79 kerätty materiaali. Aineiston analysoinnin menetelmänä käytettiin binomitestiä, korrelaatiokerrointa sekä sisällönanalyysiä, joita käyttämällä päästiin luotettaviin tuloksiin lentopahoinvoinnin syntyyn vaikuttaneista tekijöistä.

The Oak Ridges Moraine is a major physiographic feature of south-central Ontario, extending from Rice Lake westward to the Niagara Escarpment. While much previous work has largely postulated a relatively simple the origin of the moraine, recent investigations have concentrated on delineating the discernible glacigenic deposits (or landform architectural elements) which comprise the complex mosaic of the Oak Ridges Moraine. This study investigates the sedimentology of the Bloomington fan complex, one of the oldest elements of the Oak Ridges Moraine. The main sediment body of the Bloomington fan complex was deposited during early stages of the formation of the Oak Ridges Moraine, when the ice subdivided, and formed a confined, interlobate lake basin between the northern and southern lobes. Deposition from several conduits produced a fan complex characterized by multiple, laterally overlapping, fan bodies. It appears that the fans were active sequentially in an eastward direction, until the formation of the Bloomington fan complex was dominated by the largest fan fed by a conduit near the northeastern margin of the deposit. Following deposition of the fan complex, the northern and southern ice margins continued to retreat, opening drainage outlets to the west and causing water levels to drop in the lake basin. Glaciofluvial sediment was deposited at this time, cutting into the underlying fan complex. Re-advancing northern ice then closed westerly outlets, and caused water levels to increase, initiating the re-advance of the southern ice. As the southern ice approached the Bloomington fan, it deposited an ice-marginal sediment complex consisting of glacigenic sediment gravity flows, and glaciolacustrine and glaciofluvial sediments exhibiting north and northwesterly paleocurrents. Continued advance of the southern ice, overriding the fan complex, ii produced large-scale glaciotectonic deformation structures, and deposited the Halton Till. The subaqueous fan depositional model that is postulated for the Bloomington fan complex differs from published models due to the complex facies associations produced by the multiple conduit sources of sediment feeding the fans. The fluctuating northern and southern ice margins, which moved across the study area in opposite directions, controlled the water level in the interlobate basin and caused major changes in depositional environments. The influence of these two lobes also caused deposition from two distinct source directions. Finally, erosion, deposition, and deformation of the deposit with the readvance of the southern ice contributed further to the complexity of the Bloomington fan complex.

Oak chest measuring 36 cm in height 45 cm in width and 32 cm in depth. The cabinet contains 5 graduating drawers and it closes with 2 hinged doors, each bearing an arch. There are recessed brass handles on the 2 sides of the cabinet and one of these handles on each of the drawers. On the top of the cabinet there is an escutcheon engraved with “S.D. Woodruff Esq., St. Catharines, 157 Ontario”. The cabinet has a lock which is still functional and opens with a skeleton key which is part of this collection. The top 2 drawers have been lined with a piece of cardboard carefully cut to size and covered with brocade. There is some scratching on the top of the cabinet and one of the front doors is missing some of the wooden trim.
