Heat transfer coefficients in an agitated vessel using verticle-tube baffles

Data are presented to show the effect of impeller speed, impeller type, and fluid properties on the forced-convection film coefficient of heat transfer for verticle tubes in a cylindrical vessel. A generalized equation to predict the film coefficient of heat transfer on the outside of verticle tubes in an agitated vessel for both cooling and heating is also presented. This equation may be used to estimate the necessary areas of heat transfer for verticle tubes in an agitated vessel within the degree of accuracy required from most engineering calculations. This study was the first initiated to develop an equation to predict film coefficients of heat transfer for verticle tubes in an agitated vessel from fluid properties, agitator speed and system dimensions. Dunlop and Rushton (6) have developed a generalized equation to predict film coefficients of heat transfer for verticle tubes in an agitated vessel since this study was initiated. The data of this thesis do not fit the equation proposed by Dunlop and Rushton. This is probably due to the difference in system dimensions and dissimilarity between their equipment and the equipment of this thesis. In the course of this study it was further determined that for a well baffled system both radial flow and axial flow impellers have the same effect on the film coefficient. Previous investigators have proposed that the exponent of the viscosity ratio was constant. It was determined in the work of this thesis that this is not true and that the ratio is a function of the fluid properties

Mental Health and Student Athletes

The purpose of this study is to gain a better understanding of the relationship between mental health and collegiate student athletes. The participants of the study were Merrimack College student athletes and those strongly associated with Merrimack. The purpose of this study was to educate and bring awareness to mental health issues in collegiate student athletes, as well as topics associated with mental health; such as social stigma, personal stigma, social support, referral skills and resources. Participants participated in an online workshop that included three activities focused on stigma, social support and help seeking. Student athlete participants were asked to complete a post workshop evaluation. The findings from this research provided insight on the quality of the workshop as well as Merrimack College’s student athlete’s attitudes toward the importance of mental health issues, help seeking, social support and stigma

Testing two data fusion methods for multiscale and multiclass land-use/land-cover maps to improve fractional information at medium resolution

High uncertainty is found during inter-comparison of land-use/land-cover (LULC) maps derived from remote sensing imagery. Among the reasons for classification mismatch, especially in coarse maps and heterogeneous areas characterized by mixed pixels, is that the landscape heterogeneity is ignored by providing only the LULC class covering the largest portion of a pixel. Pixels are arbitrary spatial units determined mainly by the sensor’s properties and can have little relation to natural units on the ground. In fact, the use of class proportions in ground-truth training data, that better depict reality, proved to decrease the thematic accuracy of traditional LULC maps characterized by one LULC class per pixel. Because high-resolution LULC maps upscaled to coarser resolutions provide higher accuracy than natively-coarse maps, and because, except from creating new maps, integration of available ones can increase the final accuracy, during this project the potential of two data fusion methods for multi-scale (from high to coarse resolution) and multi-class maps to derive more accurate ones with fraction information at medium resolution (100m) was explored. Two data fusion models were tested in four study areas characterized by both mixed and pure-pixels by using seven LULC maps as input and a ground-truth sub-pixel database as response variable. The models’ output was then validated and compared against each individual input map, in both mixed and pure-pixels, by using the sub-pixel thematic accuracy matrix. To make more robust predictions and better answer the research questions of the study improvement of the goodness of fit of the data fusion models is needed. Despite the need of the models’ amelioration, it was observed that multiscale and multiclass data fusion improved the sub-pixel accuracy of some LULC classes compared to some of the maps used as input specially in mixed-pixels

Evaluation of the Lambs’ State of Consciousness Signs during Halal and Traditional Slaughtering

The aim of this study was to evaluate the persistence of two signs of consciousness (rhythmic breathing and corneal reflex) in lambs slaughtered according to the traditional method and Halal ritual rite. A total of 240 lambs were examined and divided into two equal groups (n = 120 each). Lambs of group A were subjected to the stunning phase by the action of an electric current on the brain, while lambs of group B were slaughtered according to the religious Halal method without prior stunning. Rhythmic breathing (RB) and corneal reflex (CR) were used as indicators of prolonged brain function, and their evaluation was carried out by the operators in three subsequent steps at 15 s, 30 s, and 90 s post-bleeding, respectively. The stunning of the lambs reduced the animal’s state of consciousness and, consequently, reduced suffering, pain, and distress. Indeed, the lambs of group B showed longer duration consciousness than the animals stunned by electrodes. The permanence of the reflexes in Halal slaughter could be reduced by introducing a reversible stunning method to make the animal temporarily unconscious. Moreover, given that our results revealed consciousness also after 90 s post-cut, the assessment of the animal’s state of consciousness in wider time intervals than those commonly used is recommended
