Research Notes: A technique for evaluating nodulation response of soybean genotypes with specific Rhizobium strains

Previous research on the interactions of Rhizobium strains with host cultivars has involved the testing of small numbers of plants with a specific strain of Rhizobium in Leonard jar assemblies (Leonard, 1943). The Leonard jar technique in our greenhouse requires frequent watering (up to twice daily) and periodic adjustment of the wick element. We have found the traditional Leonard jar assembly technique inadequate to efficiently accommodate the large plant populations required in plant selection and genetic studies of allelism and linkage

Physiotherapy Students’ Attitudes Toward Working With People With Dementia: A Cross-Sectional Survey

Aims: To understand personal, educational and clinical experiences and the attitudes of physiotherapy students towards people with dementia. Methods: Online survey questionnaire. Physiotherapy students in the last year of a two-year Masters of Physical Therapy (MPT) entry-to-practice degree program (n = 59) were surveyed. Descriptive statistics were used to analyze the data. Results: Fifty-five students participated (93%). The majority of students (n = 52/55, 77%) had at least one clinical placement working with people with dementia. Overall, 53% (n = 29/55) felt their academic training was sufficient to effectively work with people with dementia. Moreover, 82% (n = 45/55) reported their confidence was greatest working with people who could communicate well verbally. Conclusions: Disease-based knowledge was strong, yet just over half felt their academic training was sufficient to effectively work with people with dementia. The findings support the need for more training, particularly in communication strategies, to support students to effectively work with client with dementia upon graduation

Finite element analysis of the influence of a fatigue crack on magnetic properties of steel

Fatigue can affect the magnetic properties of materials due to microstructural changes. Previous investigations have shown that several structure sensitive magnetic properties, such as coercivityHc and remanenceBr, changed systematically as a result of fatigue. When approaching failure the accumulated changes in microstructure resulted in the occurrence of fatigue cracks and the magnetic properties showed dramatic changes which mainly resulted from the geometrical changes in samples due to the cracks. It was found that the remanenceBr followed the changes in stress, while the coercivityHc sometimes showed different trends. In this article the influence of the size and the position of a fatigue crack on magnetic field and magnetic induction were studied using finite element modeling. Models were constructed to simulate the geometry of the test sample and sensor. It was found that, for a given coil current in the exciting coil, the magnetic induction was mainly determined by the geometry of the crack, while the magnetic field was influenced by both the size and the position of the crack

Self-Consistency in Estimating Future Electrical Energy Consumption

A socio economic computer simulation model for the State of Oregon is described. The Oregon State Simulation Model (OSSIM) includes a thirty-seven sector model of electrical energy consumption. Coupling between this model and the OSSIM ensures self-consistent scenarios of socio economic phenomena which underlie energy consumption. One of the purposes of this effort is to help state-level decision makers understand the determinants of electricity consumption within a context of changing economic conditions
