An Approach For Collection Of Nearfield Groundwater Samples In Submerged Limestone Caverns, Aaron L. Mills, Terrence N. Tysall, Janet S. Herman

KIP Articles

Walls of submerged caves feeding Florida springs are often lined with a heavy mat of filamentous bacteria, many of which are able to oxidize reduced sulfur in groundwater migrating from the porous bedrock into the cave conduit. To determine changes in water chemistry as water passes through the microbial mat, a simple device made from standard well screen and sealed with a rubber stopper and controllable vents was installed in a hole drilled in the wall of the cave passage. The sampler was sealed in place with marine epoxy. We measured anions in water from the sampler and from the …

Landforms Of Mountainous Karst In The Middle Latitudes: Reflections, Trends And Research Problems, Ugo Sauro

KIP Articles

Research into the landforms of karst highlands in the middle latitudes began in the "Classical Karst" in the 19th century and has been marked by alternating periods of progress and stability since. In the beginning, the elementary morpho-types were recognized, in particular the circular closed depression defined as the "karst doline." Later the midlatitude karst forms were compared with those of other climatic zones, especially tropical humid karst. In recent decades many papers have been published on the morphometry, the fillings, and models of the evolution of the surface karst landforms. It has been emphasized that in the midlatitude karsts …

Environmental Controls On Organic Matter Production And Transport Across Surface-Subsurface And Geochemical Boundaries In The Edwards Aquifer, Texas, Usa, Benjamin T. Hutchins, Benjamin F. Schwartz, Annette S. Engel

KIP Articles

Karst aquifer phreatic zones are energy limited habitats supported by organic matter (OM) flow across physical and geochemical boundaries. Photosynthetic OM enters the Edwards Aquifer of Central Texas via streams sinking along its northeastern border. The southeastern boundary is marked by a rapid transition between oxygenated freshwaters and anoxic saline waters where OM is likely produced by chemolithoautotrophic microbes. Spatial and temporal heterogeneity in OM composition at these boundaries was investigated using isotopic and geochemical analyses. δ13C values for stream fine particulate OM (FPOM) (−33.34‰ to −11.47‰) decreased during regional drought between fall 2010 and spring 2012 (p<0.001), and were positively related to FPOM C:N ratios (r2=0.47, p<0.001), possibly due to an increasing contribution of periphyton. Along the freshwater-saline water interface (FWSWI), δ13CFPOMvalues (−7.23‰ to −58.18‰) correlated to δ13C values for dissolved inorganic carbon (δ13CDIC) (−0.55‰ to −7.91‰) (r2=0.33, p=0.005) and were depleted relative to δ13CDIC values by 28.44‰, similar to fractionation values attributed to chemolithoautotrophic carbon fixation pathways using DIC as the substrate. δ13CFPOMvalues also became enriched through time (p<0.001), and δ13CDIC values (r2=0.43, p<0.001) and δ13CFPOM values (r2=0.35, p=0.004) at FWSWI sites increased with distance along the southwest-northeast flowpath of the aquifer. Spatial variability in FWSWI δ13CDIC values is likely due to variable sources of acidity driving carbonate dissolution, and the temporal relationship is explained by changes to recharge and aquifer level that affected transport of chemolithoautotrophic OM across the FWSWI.

Preparing Occupational Therapy And Physiotherapy Students For Work-Related Practice: A Clinical Education Initiative At One Australian University, Kerry Adam, Jenny Strong, Lucinda Chipchase

Internet Journal of Allied Health Sciences and Practice

Purpose: Despite increasing numbers of novice occupational therapists (OTs) and physiotherapists (PTs) entering work-related practice since the early 2000s, clinical learning opportunities are often limited due to legal and insurance issues. In response, clinical educators at The University of Queensland, Australia, developed an industry consultancy service to provide clinical learning for students in this field. Students delivered injury prevention services with supervision from experienced educators. This paper describes the program and an evaluation of student learning. Method: Twenty-six students (10 OTs and 16 PTs) participated voluntarily in an evaluation of the program during 2008 and 2009. Surveys pre and post-placement …

Information Management And Delivery Of The Bible, Paul A. Soukup

Communication

In the Bible, God definitely works through human means, with all their characteristics and even with all their limitations. From the perspective of human communication, the ideas of ‘delivery systems’ or media for the Bible give only a part of the picture. The larger story describes how God’s word in the Scriptures moves from generation to generation in a variety of forms. And that story (looked at as communication) concerns information management: the discovery, preservation, recall, and expression of information. This case study of the delivery system of the Bible in mission will draw on the media ecology approach to …

Expression Of Mismatch Repair Proteins In Colorectal Cancer At Aga Khan University Hospital, Nairobi, Charles M. Wahome

Master of Medicine in Anatomic Pathology

Introduction: Microsatellite instability is one of three molecular pathways described in the pathogenesis of colorectal carcinoma. The presence of microsatellite instability in patients with colorectal cancer has implications for prognosis and family counselling. Deficiency in mismatch repair genes leads to microsatellite instability and this can be reliably demonstrated in formalin fixed paraffin embedded tissue by methods, which include immunohistochemistry for the detection of mismatch repair proteins. Local data show a disproportionately large number of younger patients with colorectal cancer compared to that documented in Caucasians. Colorectal cancer in younger ages is often attributed to deficient mismatch repair. The objective of …

Trajectory Generation For Stair Ascent Walking Using Rayleigh Oscillator, T. Afzal, Andrew B. Wright, Kamran Iqbal

Journal of the Arkansas Academy of Science

This paper describes a trajectory generation technique for stair-ascent walking. The knee, hip and ankle joint trajectory during stair ascent are generated using mutually coupled, nonlinear oscillators. The parameters of the oscillators are tuned using the harmonic balance method, which converts the nonlinear differential equations to a set of algebraic equations. Fourier analysis of data generated by stair-ascent walking is performed to extract the amplitude and the phase of the dominant frequency components for each joint trajectory. The solution for the oscillator is assumed to be a sinusoidal wave and then by harmonic balance method the parameters of the oscillator …

Changes In Cell Morphology And The Cellular Localization Of Protein Kinase Dsk1 In Schizosaccharomyces Pombe In Response To Butylated Hydroxyanisole, Jacqueline T. Humphries

Scripps Senior Theses

Dsk1 is the Schizosaccharomyces pombe functional homolog of human SRPK1, an SR protein kinase that regulates localization and function of SR protein splicing factors involved in transcription, alternative splicing, and mRNA export. It has been shown that a Dsk1 deletion strain of S. pombe is sensitive to exposure to butylated hydroxyanisole (BHA), a phenol derivative commonly used as a food preservative. Little is known about how BHA interacts with cells on a functional level, although it has been shown to be cytotoxic and tumorigenic. The aims of this thesis are to study the effect of BHA on eukaryotic cells and …

Effectiveness Of Sequential V. Standard Triple Therapy For Treatment Of Helicobacter Pylori Infection In Children In Nairobi, Kenya, Ahmed Laving, Rose Kamenwa, Shahin Sayed, Andrew Nyerere Kimang'a, Gunturu Revathi

Paediatrics and Child Health, East Africa

Background: Once the diagnosis of Helicobacter pylori is confirmed, treatment requires at least two antibiotics and an acid inhibitor for a minimum of seven days. Unfortunately, treatment failures are being frequently reported. Treatment regimens that include sequential administration of antibiotics with acid inhibitors have been developed to try and increase the rate of eradication.

Objective: To determine the effectiveness of a novel 10-day sequential therapy compared with the standard 10-day triple therapy for treatment of H. pylori infection in children.

Methods: A double-blinded, randomised, controlled trial was conducted. Children under the age of 16 years with recurrent abdominal pain associated …

Response Of Clostridium Pasteurianum Atcc 6013 To The Presence Of Solvents For Extractive Butanol Fermentation, Mar Piernavieja Hermida

Theses

Butanol is of particular interest as a renewable biofuel. This research investigated the butanol extraction by converting purified glycerol into butanol using C. pasteurianum. The effects of three organic extractive reagents were studied to assess their use in extractive fermentation of butanol. High toxicity was shown by octanol, inhibiting cell growth. Oleyl alcohol not only appeared to be non-toxic but also yielded high butanol concentrations. Methyl oleate seemed to be corrosive to the flasks used in the fermentation process. The maximum butanol yield produced using oleyl alcohol as extractive solvent was 0.436 g/g; this value was higher than any other …

Nepa And Downstream Greenhouse Gas Emissions Of U.S. Coal Exports, Elizabeth Sheargold, Smita Walavalkar

Sabin Center for Climate Change Law

As U.S. coal exports increase and new infrastructure is proposed to improve access to markets in Asia, controversy has arisen regarding the scope of environmental review that should be carried out by government. In particular, there is significant disagreement as to whether the end-use of exported coal and the emissions generated by its combustion fall within the scope of environmental review under the National Environmental Policy Act of 1969 (NEPA). This paper considers this issue, examining the requirements of NEPA and its implementing regulations, as well as current practice by Federal agencies.

Red China Going Green: The Emergence And Current Development Of Carbon Emissions Trading In The World's Largest Carbon Emitter, Xiaotang Wang

Sabin Center for Climate Change Law

This paper focuses on one of China’s efforts to engage with climate change—the establishment and development of carbon emissions trading schemes (ETSs) in the country. Section II examines the shift from command and control approaches to market mechanisms in China’s climate policy over the past two decades, which primed the domestic scene for the emergence of carbon emissions trading. Section III studies the seven regional ETS pilots due to launch later this year, the success or failure of which will to a large extent determine the future of carbon markets in not only China, but most likely the rest of …
