Austin also must be remembered. The Augustinian legacy in Milton's work
No full textWhen I started working on this project, with a limited knowledge of Augustine, but determined to spot his presence in Miltonâs poetry, I was little aware of the intricacy of the relationship between the two authors. At this stage of my research, I do subscribe to Savoyeâs opinion, that this relationship is pervasive. However, one could safely add, it is as pervasive as it is hidden, primarily because of changed cultural paradigms, so that Miltonâs references are no longer familiar to the reader.
As I have pointed out in my presentation of the state of the art, these articulations are hardly made explicit in Miltonâs Oeuvre and also in critical literature they are hardly brought to the surface. My objective has been to make them a little more visible.
I have started my own process of discovery from the works where Milton more openly (but not completely) acknowledges his Augustinian sources, although arguably mediated. As concerns Samson Agonistes, I have presented a reading through Augustinian lenses. I am by no means claiming that mine is the best of all possible readings, but through those lenses I have been able to see a coherence, in Miltonâs dramatic poem, that is not generally recognized.
On the other hand, I thoroughly agree that âone cannot simply take any English poet and turn the post-structuralist critical machine loose on him or her in good faithâ. In particular, I am aware that I have read Miltonâs works against the current critical grain which, with a powerful turn impressed by Empsonâs Miltonâs God, is continually surfacing Miltonâs idiosyncrasies in order to cancel the received picture of a Christian author. Rather, I agree with Cirillo that Miltonâs perspective is that of âa professed Christian poet whose Christian consciousness, no matter how heterodox, colored virtually everything he wrote.â.We may ask, echoing Febvre on Rabelais, âMais de quel christianisme? In accordance with very traditional, even traditionalist Milton Criticism, I think it can safely be stated that Milton is a post-Reformation religious author, and one whose endeavour to âjustify the ways of God to menâ had to come to terms with the difficult task to find signs of providential history in the aftermath of a civil war and in the adverse context of the Restoration. His last published poems deal with this problem in different terms. As readers, we can come to different conclusions as to the texts. Behind them there is the man, âest abyssus humanae conscientiae,â in front of which, after Augustine, I can only say: "nescio"
Evaluation of SAMSON for use in a South Platte decision support system
No full textDecember 1996.The South Platte River basin is a tributary of the Missouri River. Three states share the basin (Colorado, Nebraska, and Wyoming), with most of the basin in Colorado (79 percent). Colorado's population has been growing rapidly, especially in Front-Range cities, increasing the demand on water resources in the basin. Highly productive plains agriculture is also a substantial user of water resources and new uses also can be expected for wildlife and recreation. A decision support system (DSS) is being planned by the State of Colorado for water management in South Platte River Basin. Anticipated needs of the system include data development and some model development specific to the South Platte. Due to the unique characteristics of the South Platte River Basin, the implementation of this framework is expected to be slightly different from other basins in Colorado. The SAMSON (Stream-Aquifer Model for Management by SimulatiON) Model, developed in the 1980s specifically for the South Platte River Basin, has been recommended by past studies for use in a South Platte DSS. This report provides and analysis of the current SAMSON model. The conclusions of this report recommend that SAMSON in its present form not be used as part of a DSS, largely due to recent developments in modeling philosophy, application, and use. SAMSON proved the entire South Platte River Basin system could be effectively modeled, and pointed to the priorities for data collection and development. Components of SAMSON could be part of future DSS systems, but they should be separated into individual modules and evaluated individually against existing models. In summary, the analysis of SAMSON clearly show the need for a modular and data-centered approach for a South Platte DSS.Grant no. 14-08-0001-G2008/5 Project no. 09; financed in part by the Department of the Interior, U.S. Geological Survey, through the Colorado Water Resources Research Institute
Optimisation of the mineral grading wind sifter separator for coal beneficiation
No full textA research report submitted in fulfillment of the requirements for the Doctor of Philosophy in Engineering, In the Faculty of Engineering and the Built Environment, School of Chemical and Metallurgical Engineering, University of the Witwatersrand, Johannesburg, 2024The concept of wind sifting for particle separation has been successfully implemented for various concentration purposes. Diverse configurations based on this concept have been fabricated over many decades. It has been used in recycling, agriculture, electronic waste sorting, furniture, food and beverages, and mineral processing industries to some extent. The approach’s effectiveness stems from the capability of separating lighter particles from heavier ones. This study utilised an optimised version of the wind-sifter that was designed and fabricated by the author during his master's degree. The drawback experienced while testing the first prototype wind-sifting separator led to this investigation. This study used a computer simulation technique (the Lagrangian particle tracking method). This resulted in observing the effectiveness of the separation process in the newly designed separator. The design of the new separator was made flexible in its mode of operation by fabricating detachable collecting bins to the separator assembly. This means the optimised separator can be operated with or without the coal collecting bins, unlike the prototype version, which could only run with its bins. The design of the separator was done with the aid of Autodesk Inventor, and simulation was carried out using Star-CCM+TM computer software. The simulation tests were performed for different particle sizes (−6.7+3.35 mm), (−3.35+1.0 mm) and (−1.0+0.2 mm) at different airstream velocities. The optimal airstream velocities from the previous study (at a cut point of 1.6 g/cm3) were also used in this study when the separator was run with its bins. These airstream velocities were 6.0 to 4.0 m/sec, 4.2 to 2.0 m/sec and 1.7 to 1.0 m/sec for the (−6.7+3.35 mm), (−3.35+1.0 mm) and (−1.0+0.2 mm) particle sizes, respectively. A simulation was used to determine the airstream velocity ranges of the separator without collecting bins. These were 10.5 to 9.0 m/sec for the (−6.7+3.35 mm), 7.0 to 5.0 m/sec for the (−3.35+1.0 mm) and 3.5 to 2.5 m/sec for the (−1.0+0.2 mm) particles. For the –1.0 mm size faction, three particle size distributions (–1.0+0.1 mm), (–1.0+0.15 mm) and (–1.0+0.2 mm) were simulated. The best airstream velocities of 1.7 m/sec and 3.5 m/sec were achieved, respectively, for the closed and opened bins. The results of the simulation study led to the fabrication of the optimised wind sifter used in this study. From the sink and float test conducted on two sets of feed-coal (coal A and coal B), the extent to which the separator could beneficiate coal was determined. The sink and float analysis revealed that coal A has a higher ash content than coal B. Coal A, at (−1.0+0.2 mm) size iii fraction, has an ash content of 4.29% at 1.3 relative density (RD). This is followed by the (−3.35+1.0 mm) particle size with 5.55% ash content and the (−6.7+3.35 mm) size fraction with an ash content of 5.89%. At an RD of 1.5, coal A has a specific ash content of 16.65%, and coal B has an ash content of 13.56% for the (−6.7+3.35 mm) fraction. Upon separating with the wind sifter, the clean coal products from coal A have a higher ash content compared to those from coal B. Running the separator without the bins, clean coal products with cumulative ash content ranging from 22.42% to 19.44% for the (−6.7+3.35 mm), 24.61% to 21.43% for the (–3.35+1.0 mm) and 27.54% to 22.51% for the (–1.0+0.2 mm) fractions were obtained. For the particle size of (−6.7+3.3 mm) and with the bins closed, a clean coal product of 20.21% was obtained from coal A (feed coal with 37.38% ash content). A coal product with 19.55% ash content was obtained from coal B (from feed coal of 26.65% ash). A second-stage test conducted on a first-stage coal product of 23.48% ash content yielded a coal product of 21.79% ash and 80% yield for coal A at (6.7+3.35 mm). This trend was also observed for other first-stage products at the three particle sizes used in this study. The Ep values obtained from this separator ranged between 0.035 and 0.16, with the Ep values increasing as the airstream velocity was reduced. For the (6.7+3.35 mm) fraction, Ep values (Probable Error of Separation) of 0.035, 0.095, and 0.16 were obtained at 6.0, 5.0, and 4.0 m/sec air velocities, respectively. Overall, the cleanest coal product with 16.73% ash and 26.70 MJ/kg was obtained in this study from coal A at bin 2. According to the study’s results, the separator was highly adaptable. The separator could also be used for upgrading and pre- concentrating other minerals in the mineral processing industry.MM202

Latvijā ir daudz sporta uzņēmumu, kas darbojas šajā jomā, tomēr autore nolēma dibināt sporta klubu Imantas rajonā, kur šobrīd jau eksistē vairāki sporta klubi, bet tie piedāvā tikai vienu sporta pakalpojuma veidu. Līdz ar to jaunam, topošam uzņēmumam SIA „SAMSON” - bērnu un jauniešu centram- būs mazāka konkurence un vairāk iespēju popularizēt un attīstīt sporta jomu noteiktā rajonā. Mūsdienās sabiedrība sāk vairāk pievērst uzmanību savam fiziskajam stāvoklim, rūpējas par veselības uzlabošanu. Vecāki arī domā par bērnu veselību un ved bērnus uz sporta nodarbībām. Līdz ar to autorei radās ideja izveidot bērnu un jauniešu sporta centru.The aim goal of the project is Ltd. Children and Youth Centre „SAMSON” foundation. The children center will give such sport services, as karate and gymnastics. Latvia has many sports companies operating in this field, however, the author has decided to establish a sports club in Imanta district, where there are sports clubs, but they offer only one type of sports service. Consequently, Ltd. Children and Youth Centre „SAMSON” will have less competition and more opportunities to promote and develop the sport in a given area. Today, people pay more attention to their physical condition, taking care of health. Parents also think about children's health and brought children to sports activities. Thus, the author have children and youth sports center creation idea

The strange biography of Samson
No full textThe biblical story of the life of Samson hides much from the reader&&the Book of Judges has deleted from the story elements that were deemed improper for the book’s placement among the Holy Scriptures. In this article, the author shows how the Bible transforms Samson from a mythological hero, the son of a god, to a mere mortal whose extraordinary strength came through the spirit of God that rested with him so long as he kept his Nazirite vows. The biblical storyteller could not prevent the story of Samson from entering into the biblical corpus since it was a tale of tremendous popularity. He thus told it in such a way as to bring it closer to his monotheistic beliefs and world-view. In its ‘biblical’ form the story does not bring honor to the figure of Samson, and so his placement as the last of the judges in the Book of Judges prepares the reader for the establishment of the institution of kingship, in the Book of Samuel.</jats:p

Upgrading Semi-Soft Coking Coal by Hydrothermal Treatment: Caking and structural properties
No full textA dissertation submitted to the school of Chemical and Metallurgical Engineering, Faculty of Engineering and Built Environment, University of the Witwatersrand, Johannesburg. In fulfilment of the requirements for the degree of Master of Science in Engineering, in 2024.Based on the current challenges faced by the metallurgical industry in South Africa in importing quality reductants, there is an urgent need to investigate a new approach to enhance the semi-soft coal available in the country. Importing prime coking coal has increased the steel price, resulting in many downstream operations involving steel closing down in the country. With a surplus of semi-soft coking coal in South Africa, this research sought to look into this kind of abundant coal to enhance its property as a reductant for blast furnace applications. For this reason, a study was conducted on two Southern African coals, Grootegeluk (semi-soft coking coal) and Moatize (higher quality coal). Both coals were individually hydrothermally treated and then blended at different ratios to further upgrade their metallurgical properties. The as-received Moatize coal showed properties that were more of prime coking coal with high total carbon content (76.50%), a crucible swelling index of nine, a maximum dilatation of 59% and volatile matter of 20.39%. It was a highly vitrinite coal with a vitrinite reflectance of 1.28%, a higher micropore volume than mesopore volume and a very low maximum fluidity of 24 dial divisions per minute (ddpm). According to the initial test, the Grootegeluk coal sample had a crucible swelling index of 5.5, a high volatile matter of 35.02% and a low vitrinite reflectance of 0.72%. In addition, the sample had a maximum dilatation of -10%, a maximum fluidity of 3ddpm and a higher mesopore volume than the Moatize coal. Hydrothermal treatment was conducted on the coal samples at numerous temperatures (100ºC to 200ºC), at various residence times (30 to 90 minutes) and at different coal masses (300 to 600grams (g)). According to the results, the optimal hydrothermal conditions were 200ºC, 90 minutes and 600g. Another hydrothermal treatment was performed at a higher temperature and residence time of 280ºC and 180 minutes. The same sample mass of 600g was used and the result showed no further improvement. The coal samples were then blended at various Grootegeluk/Moatize ratios (15% to 50% Grootegeluk), and further hydrothermal treatment tests were carried out based on the optimum conditions achieved. Both the hydrothermal test and the blending of the coal led to a coal with volatile matter ranging from 21.46% to 23.79%, which is a required specification for metallurgical application. The total carbon of the enhanced coal blend also ranged from 68.8% to 82.10%, with total sulphur below 1%. The mesopore-micropore ratio of the treated blend was higher than the individual coal samples, which is what is expected of a metallurgical coal. Based on these findings, coke was produced and analysed to identify a coke capable of withstanding blast furnace conditions. Using the particle reactivity index (PRI), proximate analysis and the pore size distribution, 90-(50% Grootegeluk+50% Moatize)-C product was identified as the coke with the least PRI and high fixed carbon. Further investigation showed that the blending and hydrothermal treatment affected the coal’s physiochemical, rheological and micro-molecular properties. The study has established that metallurgical properties of the locally mined semi-soft coking can be enhanced solely and when mixed with a hard coal. Even though the 90-(50%GG+50%M)-C did not meet the overall specifications required for use in the blast furnace, it was identified as a suitable reductant for other metallurgical applications.(DSI/NRF) National Research Fund through the South Africa Research Chairs Initiative (SARChI) Clean Coal Technology Grant for the financial support on the research.MM202
