MEMS 411: The Amazing Renewable Race

The project’s goal was to convey the importance of renewable energy to a 6 through 12 years old audience. This demo was designed to be installed at the St. Louis Science Center. To engage a younger audience, the renewable energy demonstration had to be interactive. As a result, a design similar to a carnival game was chosen. There are 3 stations that represent wind, hydroelectric, and solar energy. In this design, it is a multiplayer interactive race that portrays renewable energy. The initial design was to have each form of energy produced by the users. The user at the hydro station would push a water pump that would bring water to the top of a water wheel, causing it to spin and produce energy. The wind energy system would involve the user pushing a air pump, a bellow, to turn a wind turbine. The solar station was designed to have a light powered by a hand crank. That light would power a solar panel. All the the renewable energy produced would then move conveyor belts that are connected to each station

Antibody responses to a Cryptosporidium parvum rCP15/60 vaccine

Cryptosporidium parvum is a zoonotic apicomplexa-protozoan pathogen that causes gastroenteritis and diarrhoea in mammals worldwide. The organism is transmitted by ingestion of oocysts, which are shed in faeces, and completes its lifecycle in a single host.^1^ C. parvum is ubiquitous on dairy operations worldwide and is one of the leading causes of diarrhoea in calves on these farms.^2,3^ Here, for the first time, we describe the antibody response in a large group of cows to a recombinant C. parvum oocyst surface protein (rCP15/60) vaccine and the antibody response in calves fed rCP15/60-immune colostrum produced by these vaccinated cows. Results of recent genotype surveys indicate that calves are the only major reservoir for C. parvum infections in humans.^4^ Human C. parvum infections are particularly prevalent and often fatal in neonates in developing countries and to immunocompromised people, such as AIDs patients.^4^ Drug therapy against cryptosporidiosis is limited and not wholly efficacious in either humans or calves^5^, making development of an effective vaccine of paramount importance. To date, there is no commercially available effective vaccine against C. parvum, although passive immunization utilizing different zoite surface (glyco)proteins has showed promise.^6-9^ All cows we vaccinated produced an antibody response to the rCP15/60 vaccine and the magnitude of response correlated strongly with the subsequent level of antibody in their colostrum. All calves fed rCP15/60-immune colostrum showed a dose-dependent absorption of antibody. Our results demonstrate that vaccination of cows with rCP15/60 successfully induces antibodies against CP15/60 in their serum and colostrum and that these antibodies are then well absorbed when fed to neonatal calves. With further research, this C. parvum vaccine may well be a practical method of conferring passive protection to calves against cryptosporidiosis. Furthermore, a specifically targeted immune-colostrum may be valuable in protection and treatment of immunocompromised human patients with cryptosporidiosis

The rural and regional ambulance paramedic : moving beyond emergency response - report to the Council of Ambulance Authorities Inc. March 2006

Serious long-term recruitment and retention problems amongst rural health workers in Australiacontribute to inequitable health service access for rural Australians. In response, new healthcaremodels with flexible workforce roles are emerging including expanded-scope paramedic roles.This research project was born from the view that expanding ambulance paramedics’ scope ofpractice offers the potential to improve patient care and the general health of the community.New healthcare models with flexible workforce roles are clearly needed in rural Australia andexpanded-scope paramedic roles are valuable innovations

Experiencing Grace: A Review of the Empirical Literature

Positive psychologists have used science to understand many virtues but have only just started to study grace, recently defined as ‘ . . . the gift of acceptance given unconditionally and voluntarily to an undeserving person by an unobligated giver’. The purpose of the current article is to provide a systematic review of all empirical studies (published and unpublished) on grace. Broadly, the empirical study of grace has focused on what people believe and how people experience both divine and human grace. Additionally, empirical attention has shifted to explore outcomes of grace-based interventions (e.g., congregation-wide interventions, marital interventions). In general, beliefs and experiences of grace were associated with (a) positive mental health outcomes, (b) religiosity, (c) virtue development, and (d) interpersonal functioning. Human grace has not been extensively explored and divine grace has been studied mostly among Christians; future studies should address these limitations and explore causal relationships

Pharmacokinetics of a Novel Sublingual Spray Formulation of the Antimalarial Drug Artemether in Healthy Adults

The pharmacokinetics of sublingual artemether (ArTiMist) was investigated in two open-label studies. In study 1, 16 healthy males were randomized to each of four single-dose treatments administered in random order: (i) 15.0 mg of sublingual artemether (5 × 3.0 actuations), (ii) 30.0 mg of sublingual artemether (10 × 3.0 mg), (iii) 30.0 mg of sublingual artemether (5 × 6.0 mg), and (iv) 30.0 mg of artemether in tablet form. In study 2, 16 healthy males were randomized to eight 30.0-mg doses of sublingual artemether given over 5 days as either 10 3.0-mg or 5 6.0-mg actuations. Frequent blood samples were drawn postdose. Plasma artemether and dihydroartemisinin levels were measured using liquid chromatography-mass spectrometry. Population compartmental pharmacokinetic models were developed. In study 1, sublingual artemether absorption was biphasic, with both rate constants being greater than that of the artemether tablets (1.46 and 1.66 versus 0.43/h, respectively). Relative to the tablets, sublingual artemether had greater bioavailability (≥1.24), with the greatest relative bioavailability occurring in the 30.0-mg dose groups (≥1.58). In study 2, there was evidence that the first absorption phase accounted for between 32% and 69% of the total dose and avoided first-pass (FP) metabolism, with an increase in FP metabolism occurring in later versus earlier doses but with no difference in bioavailability between the dose actuations. Sublingual artemether is more rapidly and completely absorbed than are equivalent doses of artemether tablets in healthy adults. Its disposition appears to be complex, with two absorption phases, the first representing pregastrointestinal absorption, as well as dose-dependent bioavailability and autoinduction of metabolism with multiple dosing

The occupation of a box as a toy model for the seismic cycle of a fault

We illustrate how a simple statistical model can describe the quasiperiodic occurrence of large earthquakes. The model idealizes the loading of elastic energy in a seismic fault by the stochastic filling of a box. The emptying of the box after it is full is analogous to the generation of a large earthquake in which the fault relaxes after having been loaded to its failure threshold. The duration of the filling process is analogous to the seismic cycle, the time interval between two successive large earthquakes in a particular fault. The simplicity of the model enables us to derive the statistical distribution of its seismic cycle. We use this distribution to fit the series of earthquakes with magnitude around 6 that occurred at the Parkfield segment of the San Andreas fault in California. Using this fit, we estimate the probability of the next large earthquake at Parkfield and devise a simple forecasting strategy.Comment: Final version of the published paper, with an erratum and an unpublished appendix with some proof
