The development of a modified 206 alloy whose composition was optimized to minimize hot tearing during semi-solid forming was reported. The effect of varying silicon, copper and iron contents was investigated using a design of experiment (DOE) approach. Semi-solid slurries were prepared using the SEED process and injected into a high pressure die casting press. The hot tearing sensitivity results were reported for different alloy variants. The microstructure evolution during the semi-solid preparation was presented along with actual die cast components. The effects of silicon, copper and iron on mechanical properties in the T7 condition were also analyzed. Beyond the benefit of reducing hot tearing, it is shown that the tensile and fatigue properties remain compatible with the automotive industry requirements.

Jean piaget, one of the most influential theorists in developmental psychology, assumed that formal thought, characterized by the development of an individual’s logical capacities, was the last stage of adult thinking. In this article, we review how the brain evolved, describing its main structures, and examining each cerebral hemisphere’s specific functions. Evidence is also provided for the production of new neurons and new connections between them, forcing a revision of old theories about the decline of intellectual functions in the elderly. We then consider Jones’ theories X and Y, and the different definitions of intelligence (fluid vs. crystallized, and qualitative vs. quantitative), and how these perspectives have influenced the way we see intelligence. Evidence supporting the addition of another stage, named post-formal thought, is examined in the context of gerontagogy. Dialectical thought characterizes this stage, and developing wisdom is its main goal. We examine the two basic principles of dialectical thought, namely the principle of contradiction and the principle of relativity of everything. It is suggested that the learning of wisdom should be the focus of future university programs to educate the elderly.

This article presents a 2017 LiDAR-DEM guided 1-m resolution examination of field-surveyed elevation and soil property variations (5 × 5 m spacings) conducted in 1977 across a hummocky New Brunswick field used for potato production. This examination revealed that the field incurred minor elevation differences likely due to upslope erosion as revealed through increasing Sand % and CF % with increasing elevation, and increasing Silt % along low-lying areas. Soil moisture, field capacity, permanent wilting and nitrate nitrogen (NO3-N) also increased at downslope locations. Directly as well as indirectly, soil pH, ammonium nitrogen (NH4-N), Caesiump>137p> (Csp>137p>) and Mehlich-3 extracted Ca, Mg, K, Fe, Mn, Cu, and Zn were likewise affected by topographic location. Factor analyzing these variables led to: 1) a Soil Loss Factor that captured 24% of the textural variations;2) a Soil-Cropping Factor accounting for 16% of the N, p, K, Ca, Mg, Mn variations;3) a Soil Organic Matter (SOM) Factor relating 9% of the in-field variations for SOM, Fe, Zn, Cu to via organo-metal complexation and low NO3-N retention. Many of the topographic variations increased or decreased with the metric DEM-projected depth-to-water index (DTW) index. This index was set to 0 along DEM-derived flow channels with minimum upslope flow-accumulation areas of 0.1, 0.25, 0.5, 1 or 4 ha. Among these, the DTW > 4 ha threshold was useful for reproducing the textural variations, while the DTW > 0.25 ha threshold assisted in capturing trends pertaining to moisture retention and elemental concentrations.

N2O represents a popular oxidizer for hybrid rocket motors for a variety of reasons, including safety, ease of access and self-pressurization. It is often used as a saturated two-phase fluid in these applications to take advantage of self-pressurization. Recent interest in using this oxidizer in regeneratively cooled engines requires a detailed heat transfer process analysis to the coolant, in order to quantify performance. Since the injection of N2O typically takes place in the two-phase region, our study focuses on heat transfer rates in this region, and extends the region to include superheated vapor. This analysis is critical for these cooling applications, because the exothermic decomposition nature of N2O also means that unchecked heating in the superheated region may result in a runaway reaction in the cooling passages. Furthermore, provided that sufficient heat transfer rates are available, N2O is expected to accelerate in the cooling passages due to Rayleigh flow effects much like those of a calorically perfect gas. The proximity of superheated N2O to its saturated vapor curve, at the conditions studied here, makes the suitability of a perfect gas model questionable, but that benchmarks is still useful. This paper presents the development of an experimental apparatus （a ＂Rayleigh tube＂）, specifically designed to study this problem, and test the analytical methods developed to model it. Since we focus on the development of the apparatus, the data presented were uses primarily calorically perfect gas surrogates, but the goal is to apply the apparatus and method to N2O. The design and construction of the Rayleigh tube is presented, along with preliminary results with perfect gases. Finally, we present preliminary results on heated N2O flow. Using a simple model for predicted dry-out point, we investigate where superheating may be expected to occur. We present estimates of critical heating and compare them to the heat required to achieve self-decomposition.

Introduction: Rural residents are at higher risk for a depressive disorder than their non-rural counterparts. Recent research has indicated that co-morbidities are also associated with depression. Health service deficits (HSDs) is an analytic concept that facilitates the examination of how a population uses health services relevant to their condition. A HSD is present when, over the preceding 12 months, an individual has had no health insurance, no specified health care provider, deferred medical care due to cost, or did not have a routine medical exam. Research has shown a high prevalence of HSDs in populations with individual chronic conditions. No study that we know of has examined if there is an association between the constellation of chronic conditions of depression and the co-morbidities of asthma, arthritis, and diabetes, with HSDs. Methods: 2011 Behavioral Risk Factor Surveillance Survey (BRFSS) data were analyzed to identify important dimensions of the epidemiology of depression by ascertaining whether there were differences in the prevalence of health service deficits in rural versus non-rural adults with depression and at least one additional chronic disease (arthritis, asthma, or diabetes). Data analyses entailed both bivariate and multivariate techniques. All analyses were performed on weighted data. Results: Logistic regression analysis performed using the presence of at least one HSD as the dependent variable yielded that for US adults with lifetime depression those who were African American, Hispanic and other/multiracial in comparison to Caucasian had higher odds of having at least one health service deficit. Low socioeconomic status (SES) and middle SES in comparison to high SES were also risk factors for US adults with lifetime depression having at least one HSD. Rural residency in comparison to non-rural residency also emerged as an independent risk factor (for US adults with lifetime depression having at least one HSD. Chronic disease, however,
