A Complete Redesign of Freshmen Engineering Course

This interactive session will provide the audience with a full description of the redesign of the freshmen engineering course at Fairfield University. In addition, participants will be led through several of the active learning experiences similar to those used in the course, thus having the opportunity to experience the class first hand. The session will cover: the history of the class, the backward design process used to revitalize the course, the linkages made between course outcomes, course goals, accreditation requirements, and the University’s core pathways, and, finally, it will conclude with results and feedback on how effective the redesign was. Participants will also get to have some time for small and large group reflection on what was learned

Transverse momentum versus multiplicity fluctuations in high-energy nuclear collisions

We discuss recently measured event-by-event fluctuations of transverse momentum and of multiplicity in relativistic heavy-ion collisions. It is shown that the non-monotonic behavior of the p_T-fluctuations as a function of collision centrality can be fully explained by the observed non-monotonic multiplicity fluctuations. A possible mechanism responsible for the multiplicity fluctuations is also considered.Comment: 5 pages, 3 figures, revised & extended, to appear in Phys. Rev.

Hubungan Antara Asupan Protein Dan Zat Besi Dengan Kadar Hemoglobin Mahasiswa Program Studi Pendidikan Dokter Angkatan 2013 Fakultas Kedokteran Universitas Sam Ratulangi

: Hemoglobin is the oxygen-carrying compound in red blood cells. Someone hemoglobin level scan be affected by several other factors: age, gender, systemic disease and diet. Nutrient intake plays a role in the formation of redblood cells. Disruption of the formation of redblood cells could be due to lack of food consumed contains essential nutrients such as iron, folic acid, vitamin B12, protein, vitamin C and other important nutrients. This study aims to determine the relation ship between the intake of protein and iron in hemoglobin level student of medical education force in 2013 Sam Ratulangi University School of Medicine. The design is an analytical study using cross-sectional approach. The study sample is determined and carried out systematic random sampling proportional to the gender of men and women and who met the inclusion criteria sample amounted to75 people. Data were collected through questionnaires and food recall by measuring hemoglobin levels, then the data were analyzed using the Spearman rank test. Protein intake is less 52.0%, 16.0% protein and enough protein intake over 32.0%. Iron intake less than 98.7% and 1.3% more protein intake. Normal hemoglobin levels of 93.3% and 6.7% is not normal. Conclusion: The results of the study with Spearman rank test for protein and hemoglobin levels obtained p-value is 0.138 (p>α=0.05) which means that there is no significant relationship between iron intake with hemoglobin levels. For intake of iron and hemoglobin levels obtained p value is 0.198 (p>α=0.05), which means there is nosignificant relationship between iron intake with hemoglobin levels

Developing a Measure of Psychological Aggression: Stage 2

Current research indicates that psychological aggression can lead to physical aggression. Thus, accurate measures of psychological aggression can be used to quell future physical aggression. However, unsound psychometric properties and fragmented definitions have diminished the accuracy of current psychological aggression scales. The purpose here is to create a sound psychological aggression scale. This part of the study focused on pilot testing preliminary items written to capture behaviors that constitute psychological aggression. An analysis revealed that some preliminary items required removal because of their abnormal distributions. The next step is to field test the items to establish the factor structure of the new scale

The prevalence of visual disorders in the juvenile delinquency population

Background: Juvenile delinquent and learning disabled populations have many common characteristics. Similarities have been found in their visual systems. This study describes the visual system of a population of juvenile delinquents from Folsom, California. Methods: The records of complete analytical exams which were performed by one examiner were obtained and a data base was used to create descriptive statistics on the 477 subjects. Findings are compared to OEP Expected Values, Morgan\u27s Normative Values, case analysis, and current studies in the literature regarding the visual profile of juvenile delinquents and the learning disabled. Results: The study revealed that the Folsom, California juvenile delinquent population has significantly decreased accommodation and vergence skills at near when compared with OEP Expected Values and Morgan\u27s Normative Values. They are a highly symptomatic group complaining of blur, headaches, and losing place while reading. Visual perception and ocular motility problems also predominate. Conclusions: There appears to be a significant need for plus nearpoint lenses and vision training for visual perception and ocular motilities among the juvenile delinquent population

Irreversible Performance of a Quantum Harmonic Heat Engine

The unavoidable irreversible losses of power in a heat engine are found to be of quantum origin. Following thermodynamic tradition a model quantum heat engine operating by the Otto cycle is analyzed. The working medium of the model is composed of an ensemble of harmonic oscillators. A link is established between the quantum observables and thermodynamical variables based on the concept of canonical invariance. These quantum variables are sufficient to determine the state of the system and with it all thermodynamical variables. Conditions for optimal work, power and entropy production show that maximum power is a compromise between the quasistatic limit of adiabatic following on the compression and expansion branches and a sudden limit of very short time allocation to these branches. At high temperatures and quasistatic operating conditions the efficiency at maximum power coincides with the endoreversible result. The optimal compression ratio varies from the square root of the temperature ratio in the quasistatic limit where their reversibility is dominated by heat conductance to the temperature ratio to the power of 1/4 in the sudden limit when the irreversibility is dominated by friction. When the engine deviates from adiabatic conditions the performance is subject to friction. The origin of this friction can be traced to the noncommutability of the kinetic and potential energy of the working medium.Comment: 25 pages, 7 figures. Revision added explicit heat-transfer expression and extended the discussion on the quantum origin of frictio

No gender-related bias in COPD diagnosis and treatment in Sweden: a randomised, controlled, case-based trial.

Introduction:COPD is a major cause of morbidity and mortality. The prevalence, morbidity and mortality of COPD among females have increased. Previous studies indicate a possible gender bias in the diagnosis and management of COPD. The present study aims to determine if there is gender bias in the management of COPD in Sweden.Methods:This was a double-blind, randomised (1:1), controlled, parallel-group, web-based trial using the hypothetical case scenario of a former smoker (40 pack-years and quit smoking 3 years ago) who was male or female. The participants were blind to the randomisation and the purpose of the trial. The case progressively revealed more information with associated questions on how the physician would manage the patient. Study participants chose from a list of tests and treatments at each step of the case scenario.Results:In total, 134 physicians were randomised to a male (n=62) or a female (n=72) case. There was no difference in initial diagnosis (61 (98%) male cases and 70 (97%) female cases diagnosed with COPD) and planned diagnostic procedures between the male and female cases. Spirometry was chosen by all the physicians as one of the requested diagnostic tests. The management of the hypothetical COPD case did not differ by sex of the responding physician.Conclusion:In Sweden, diagnosis and management of a hypothetical patient with COPD did not differ by the gender of the patient or physician

Relativistic Klein-Gordon charge effects by information-theoretic measures

The charge spreading of ground and excited states of Klein-Gordon particles moving in a Coulomb potential is quantitatively analyzed by means of the ordinary moments and the Heisenberg measure as well as by use of the most relevant information-theoretic measures of global (Shannon entropic power) and local (Fisher's information) types. The dependence of these complementary quantities on the nuclear charge Z and the quantum numbers characterizing the physical states is carefully discussed. The comparison of the relativistic Klein-Gordon and non-relativistic Schrodinger values is made. The non-relativistic limits at large principal quantum number n and for small values of Z are also reached.Comment: Accepted in New Journal of Physic

Transport and Magnetic Studies on the Spin State Transition of Pr1-xCaxCoO3 up to High Pressure

Transport and magnetic measurements and structural and NMR studies have been carried out on (Pr1-yR'y)1-xAxCoO3 {R'=(rare earth elements and Y); A=(Ca, Ba and Sr)} at ambient pressure or under high pressure. The system exhibits a phase transition from a nearly metallic to an insulating state with decreasing temperature T, where the low spin (LS) state of Co3+ is suddenly stabilized. For y=0, we have constructed a T-x phase diagram at various values of the external pressure p. It shows that the (T, x) region of the low temperature phase, which is confined to a very narrow region around x=0.5 at ambient pressure, expands as p increases, suggesting that the transition is not due to an order-disorder type one. For the occurrence of the transition, both the Pr and Ca atoms seem to be necessary. The intimate relationship between the local structure around the Co ions and the electronic (or spin) state of Co3+ ions is discussed: For the smaller unit cell volume or the smaller volume of the CoO6 octahedra and for the larger tilting angle of the octahedra, the temperature of the transition becomes higher. The role of the carriers introduced by the doping of the A atoms, is also discussed. By analyzing the data of 59Co-NMR spectra and magnetic susceptibilities of Pr1-xCaxCoO3 the energy separations among the different spin states of Co3+ and Co4+ are roughly estimated.Comment: 15 pages, 15 figures, 2 tables, submitted to J.
