Thesis (M.Sc. (Pasture Science)) -- University of Limpopo, 2014 / Forage sorghum is widely grown in South Africa as annual summer forage to supplement pasture production for sheep, beef and dairy cattle. A number of sorghum cultivars are available commercially, and periodically some cultivars are added while others are withdrawn from the market. The potential yield figures and the nutritive value of these forage sorghum cultivars are generally not known. The management practices that improve forage sorghum production and quality include the time of planting and time of harvesting. The genetic makeup of different forage sorghum cultivars also accounted for a portion of the production and quality. A field experiment was conducted at Dewageningsdrift Experimental Farm (DWD), Moloto, Gauteng and Nooitgedacht Agricultural Development Center (NGD), Ermelo, Mpumalanga to study the influence of planting date on the growth potential of different forage sorghum cultivars. Three planting dates were used: mid-December 2006, mid-January 2007 and mid-February 2007. Thirteen different cultivars were incorporated in the trial to evaluate influence of the breeding history. The cultivars were defoliated at three different stages: cut repeatedly at six weekly intervals (Dt 1), cut repeatedly when it reached a grazing stage (± 800 mm high) (Dt 2) and once at the silage stage (soft dough) (Dt 3). At DWD the average total dry matter (TDM) productions, for the six week cutting treatment (Dt 1), were 10760 kg/ha, 5195 kg/ha and 1944 kg/ha for December, January and February planting date respectively. For the same treatment, at NGT, the average TDM productions were 6396 kg/ha and 1737 kg/ha for December and January respectively. The February planting resulted in the poor germination and seedling emergency. The seedlings did not survive due to low temperatures. The minimum of 13 ºC and 11.8 ºC as well as the maximum of 24.1 ºC and 23.0 ºC in February and March were below the required germination temperature (15 ºC). The highest producers that is available in the market were Jumbo, Sentop, Piper, Kow Kandy, and Sugargraze. Defoliated repeatedly at grazing stage (Dt 2), at DWD, resulted in average TDM productions of 8541 kg/ha, 4950 kg/ha and 2683 kg/ha for December, January and February, respectively. At NGT the average TDM productions were 7769 kg/ha and 3010 kg/ha for December and January respectively. The highest producers were Jumbo, Kow Kandy, Piper, Sentop and Sugargraze. The average TDM productions at the silage stage (Dt 3), at DWD, were 17923 kg/ha, 15015 kg/ha and 2529 kg/ha for December, January and February respectively. At NGT the average TDM production iii was 11856 kg/ha and 5350 kg/ha for December and January, The highest producers were Jumbo, Sugargraze, Kow Kandy, Sentop and Kow Kandy.December planting proved to be the best planting date for optimum DM production, compared to later plantings in January and February.

water sorption isotherms of destoned and ground saiadey Jaul type dates were obtained at 30,40.50 C.using the gravimetric methods.Data were analyzed by applying the GAB,BAT ,Smith,Iglesias and Chrife,Halsey ,Henderson and Oswin Models.Isosteric heat of sorption value was calculated using the Clausius-Clapeyron Equation and tried to be as afunction of moisture content of dates. It was found that the experimental data fitted well to ,smith ,I glesias and Chirife ,Halsey, Henderson and Oswin equation, which are suitable for high sugar foods.Isosteric heat of sorption for dates varied from 0,9 to - 1,84 KJ/mol as moisture content changed from 11,0 to 18,0%.

In this dissertation, we study the single machine scheduling problem with an objective of minimizing the total completion time subject to release dates. The problem, denoted 1|rj £UCj ,was known to be strongly NP-hard and both theoretically and practically important. The focus of the research in this dissertation is to develop the efficient algorithms for solving the 1|rj|£UCj problem. This thesis contains two parts. In the first part, the theme concerns the approximation approach. We derive a necessary and sufficient condition for local optimality, which can be implemented as a priority rule and be used to construct three heuristic algorithms with running times of O(n log n). By ¡¨local optimality¡¨, we mean the optimality of all candidates whenever a job is selected in a schedule, without considering the other jobs preceding or following. This is the most broadly considered concepts of locally optimal rule. We also identify a dominant subset which is strictly contained in each of all known dominant subsets, where a dominant subset is a set of solutions containing all optimal schedules. In the second part, we develop our optimality algorithms for the 1|rj |£UCj problem. First, we present a lemma for estimating the sum of delay times of the rest jobs, if the starting time is delayed a period of time in a schedule. Then, using the lemma, partially, we proceed to develop a new partition property and three dominance theorems, that will be used and have improved the branch-and-bound algorithms for our optimization approach. By exploiting the insights gained from our heuristics as a branching scheme and by exploiting our heuristics as an upper bounding procedure, we propose three branch-and-bound algorithms. Our algorithms can optimally solve the problem up to 120 jobs, which is known to be the best till now.

A combined field and laboratory investigation of the primarily volcanic Roskruge range, Pima County, Arizona, produced the following results: The rocks in the area fall into three major and several minor divisions. The major groups are: (1) The pre-Laramide dark-colored andesites and sediments that floor the range. A K-Ar date on one of the andesites produced a number, 108 m. y. , on a whole rock analysis. (2) The brightly colored and widespread Laramide volcanics and an associated hypabyssal pluton at Cocoraque Butte, which gave K-Ar mineral ages in the 74 m. y. to 66 m. y. spread. (3) The mid-Tertiary potassic basaltic andesites found on an eroded plain that is cut into the Laramide volcanics. These dark-colored extrusives were dated at 23 m. y. by whole rock K-Ar. Amongst the minor units in distribution is the petrographically unusual Recortado ash flow, a small 13 m. ye old unit that preserves a vitrophyre just above its base. Also included in the miscellaneous group of units are the post-orogenic true basalts, which appear as dikes and as a flow(?) at Brawley Wash and which gave whole rock K-Ar dates of about 10 m. y. Initial strontium 87/86 ratios indicate that the Laramide and mid-Tertiary rocks (including the Recortado ash flow) have values ranging from . 7056 to .7092, while the Brawley Wash basalt has a true deep-seated basalt ratio of .7038. The combination of radiochemical assay, petrographic and field study, and isotopic data has established good gross correlation with the already known sequence of formations and plutons in the Tucson Mountains.

In the United States as many as 15% of births occur before 39 weeks because of elective inductions or cesarean sections. This qualitative study employs a grounded theory approach to understand the decisions women make of how and when to give birth. Thirty-three women who were pregnant or had given birth within the past two years participated in key informant or small group interviews. The women’s birth narratives and reflections reveal how they construct the uncertainty of their due dates and how this construction influences their birth decisions. Problematic integration theory is used to analyze this construction and identify points of influence. The results suggest that women construct the uncertainty of due dates as a reason to wait on birth and as a reason to start the process early. The results suggest that information about a baby’s brain development in the final weeks of pregnancy may persuade women to remain pregnant longer. The results demonstrate the utility of using problematic integration theory to understand a medical situation that is the result of epistemological and ontological uncertainty. The analysis suggests the existence of a third type of uncertainty, axiological uncertainty. Axiological uncertainty is rooted in the values and ethics of outcomes.

O tema surgiu em pesquisas sobre separação conjugal e guarda de filhos do Instituto de Psicologia da Universidade do Estado do Rio de Janeiro, nas quais se observou que as dissoluções que ocorreram nas datas festivas eram relevantes. Foram desenvolvidas análises bibliográficas sobre casamento, dissolução da conjugalidade, comemorações, memórias e rituais. Devido à interdisciplinaridade da temática realizou-se estudos em Psicologia, Antropologia, Direito, História e Sociologia. Pretendeu-se verificar quais os sentidos atribuídos pelos ex-cônjuges à data comemorativa na qual ocorreu a separação. Buscou-se constatar se houve alteração ou reconfiguração do significado das datas após o rompimento e visou-se apresentar reflexões que possam auxiliar a prática clínica e jurídica, mediante a atuação do profissional psicólogo nas questões tangentes à separação conjugal. A metodologia utilizada foi de História de Oral História de vida. Foram entrevistados quatro sujeitos, um rapaz que tomou a iniciativa no seu aniversário, uma moça que anunciou a decisão no aniversário de vinte seis anos de casamento, uma mulher que recebeu a notícia no Natal e um homem que foi comunicado no Ano Novo. Todos são do Estado do Rio de Janeiro e de classe média. A partir do discurso foi realizada a análise qualitativa dos dados, classificando-se as respostas em categorias essenciais à pesquisa. Como resultados verificou-se, no que se refere às datas comemorativas, que os entrevistados vivenciaram esses momentos como se estas possuíssem algo de mágico. Como se nestas épocas todos os problemas pudessem ser colocados de lado e tréguas pudessem ser feitas. Entretanto, os relatos mostraram que a tal mágica não ocorreu, as dificuldades continuaram expostas e, pelo contrário, o clima do evento evidenciou as convergências ficando difícil progredir como se nada estivesse acontecendo. Os sujeitos que tiveram a iniciativa em terminar com o relacionamento afirmaram que as datas das bodas de casamento e o aniversário natalício deram força e coragem que não tinham tido até aquele momento. Este ato favoreceu a sensação de realização e conquista que, no entanto, vinham misturada de dor, frustração e mágoa. Os sujeitos que receberam o comunicado da decisão do rompimento do casamento no Natal e no Réveillon reconheceram que a noticia configurou-se numa surpresa impactante, ao ponto de provocar silêncio. Identificou-se que não houve reconfiguração nos sentidos atribuídos às datas comemorativas, ao contrário o rompimento nestes eventos sociais fortaleceram o acontecimento. No entanto, foi possível perceber uma adição ao calendário oficial. O Natal, o Réveillon, as bodas e o aniversário é, também, o dia do rompimento conjugal. Soma-se marcos e fortifica-se o evento na memória dos sujeitos que vivenciaram estas histórias. Dentre as contribuições para a prática da Psicologia Jurídica e da clínica evidenciou-se que estes profissionais devem estar atentos ao caráter cíclico das festividades que estão nos calendários, configurando-se em momentos de transição, de inícios e fins. / The thesis has been elaborated having an objective to underline the vicissitudes which may refer to the fact of some conjugal breaking-offs taken place on the commemorative dates. The topic resulted from researches of the Institute of Psychology of the State Rio de Janeiro in respect of conjugal dissolution and guardianship of children. Through the said research it has been observed that dissolutions which occurred on festive dates were relevant in this regard. There have been conducted certain bibliographical analyses on marriage, conjugal dissolution, commemorations, remembrances and rituals. Due to correlation with other subjects certain study has been realized on such disciplines as Psychology, Anthropology, Civil Law, History and Sociology. It has been an intention to verify meanings attributed by ex-husband and ex-wife to the commemorative date on which the dissolution occurred. The research has been made to ascertain whether there has been alteration or reconfiguration of the date meanings after the dissolution event with a purpose to present certain reflections which may contribute to clinical and juridical practice through the performance of the professional psychologist within the areas related to the issues on conjugal dissolution. The methodology of Oral History Life History has been applied. Four persons have been interviewed: a guy, who took initiative on his birthday, a girl who announced the decision on her twenty sixth wedding anniversary, a woman who received such news on Christmas day and a man who was communicated that information on the New Years Day. They all are from the State Rio de Janeiro and are representatives of the media class. The qualitative data analysis has been made to classify responses into essential categories to align with the research. As far as commemorative dates are concerned, it has been verified that interviewees experienced those moments in such a way as if those moments were of some magical nature. As if at that time all the problems could have been put aside and a truce could have been concluded. However, results have demonstrated that such magic did not occur and problems continued to exist, and on the contrary, the climate of the event proved that it was difficult for convergence to progress as if nothing has happened. Those persons who took an initiative to terminate the relationships confirmed that the dates of wedding anniversary and birthdays gave them such a strength and courage which they have not had before that moment.

Fundação de Amparo a Pesquisa do Estado de São Paulo / The objectives of this dissertation were to determine the cardinal temperatures of sweet potato and compare the simulation of node appearance with the plastochron model (linear) and with Wang and Engel model (nonlinear) and the best way input air temperature in the models and to assess the effect of planting dates on tuber initiation and storage root yield of sweet potato in a subtropical environment. Models calibration and the test were with data of number of nodes on the main stem of sweet potato plants, collected at seven planting dates in 2010, 2011 and 2012 growing seasons. The tuber initiation and storage root yield were assessed in an experiment with four planting dates in 2011 and 2012 growing seasons. The experiments were conducted in the experimental area of the Department of Plant Science, UFSM, Santa Maria, RS, with cultivar Princesa at planting density of de 25.000 plants ha-1. The experiment was a complete randomized block design with four replications. The version with mean temperature was superior to the version with the minimum and maximum temperature as input in both models. The plastochron and Wang and Engel models showed similar performance, with RMSE ranging from 2.1 to 2.2 nodes respectively. Both models can be used to simulate the development of sweet potatoes when it is cultivated in the recommended period. Outside this period is suggested to use the model of Wang and Engel. The conditions of temperature and photoperiod modified the tuber initiation in each planting date, indicating that short photoperiods accelerate its occurrence. The storage root yield was higher when planting was done in late winter due to the longer duration of tuber bulking which coincided with periods of high solar radiation and temperatures favorable to the growth and development of sweet potato.

A calibração e o teste dos modelos foram feitos através de dados de número de nós na haste principal de plantas de batata-doce, coletados em sete datas de plantio nos anos 2010, 2011 e 2012. O início de tuberização e a produtividade foram avaliados em um experimento com quatro datas de plantio em 2011 e 2012. Os experimentos foram conduzidos na área experimental do Departamento de Fitotecnia da UFSM, Santa Maria, RS, com a cultivar Princesa na densidade de plantio de 25.000 plantas ha-1. O delineamento experimental foi blocos ao acaso com quatro repetições. Melhor predição dos modelos foi obtida com o uso das temperaturas cardinais 12 °C, 30 °C e 40 °C. A versão da temperatura média diária do ar foi superior a temperatura mínima e máxima diária do ar em ambos os modelos. Os modelos plastocrono e Wang e Engel apresentaram desempenho semelhante, com a RQME variando de 2,1 a 2,2 nós respectivamente. Os dois modelos podem ser utilizados para simular o desenvolvimento vegetativo da batata-doce quando cultivada na época recomendada. Fora desse período sugere-se usar o modelo de Wang e Engel. As condições de temperatura e fotoperíodo modificaram o início de tuberização em cada data de plantio, indicando que fotoperíodos curtos aceleram sua ocorrência. A produtividade de raízes tuberosas foi maior quando o plantio foi realizado no final do inverno, em decorrência da maior duração da fase de acumulação de amido, que coincidiu com os períodos de alta radiação solar incidente e temperaturas favoráveis ao crescimento e desenvolvimento da batata-doce.

The Ceramics of Tiwanaku: What does the Variability Mean?Increasingly researchers observe a wide range of variability in Tiwanaku ceramics, not only in distant regions but also within the Tiwanaku heartland of the south Titicaca Basin. This variation makes it difficult to apply the three phase or five phase chronologies developed earlier this century, as is evidenced by the wide variety of adaptations made to accommodate new data into the old periodizations. What emerges from this newly described variability is a timeline for Tiwanaku that is both shorter and more complex than previously thought. This contradicts models of Tiwanaku as a monolithic, highly centralized state with few definable periods of distinct ceramic production or decorative style. / Cada vez más investigadores notan una amplia gama de variabilidad en la cerámica de Tiwanaku, no solo en las regiones a mucha distancia, sino también en la región central de Tiwanaku, al sur de la cuenca del lago Titicaca. Esta situación hace difícil aplicar las cronologías de tres y cinco fases desarrolladas a comienzos de este siglo, como lo evidencia la gran variedad de modificaciones hechas en ellas para poder acomodar los nuevos datos. Lo que emerge de esta nueva información es que el desarrollo temporal de la entidad política Tiwanaku es, simultáneamente, más corto y complejo de lo que se pensaba anteriormente. Esto contradice los modelos de Tiwanaku como un estado monolítico altamente centralizado, con algunos pocos periodos definibles de producción cerámica o estilo decorativo.
