ISU’s proposed research will (1) develop methods for designing clean and efficient burners for low‐Btu producer gas and medium‐Btu syngas, (2) develop catalysts and flow reactors to produce ethanol from medium‐Btu synthesis gas, and (3) upgrade the BECON gasifier system to enable medium‐Btu syngas production and greatly enhanced capabilities for detailed gas analysis needed by both (1) and (2). This project addresses core development needs to enable grain ethanol industry reduce its natural gas demand and ultimately transition to cellulosic ethanol production.

Cloreto de mepiquat, thidiazuron e ethephon aplicados no algodoeiro em Ponta Porã, MS

O objetivo do presente estudo foi avaliar os efeitos de diferentes dosagens de cloreto de mepiquat, thidiazuron e ethephon, aplicadas parceladamente no algodoeiro (Gossypium hirsutum L.) na Fazenda Itamarati, Ponta Porã, MS. As dosagens de cloreto de mepiquat foram: (0; 12,5 + 12,5 + 25,0 = 50; 25 + 25 + 25 = 75; 0 + 50 + 50 = 100; 12,5 + 62,5 + 50 = 125) g ha-1, com aplicações efetuadas aos 34, 47 e 62 dias após a emergência (DAE) em 1993/94, e aos 42, 60 e 73 DAE, em 1994/95, enquanto o thidiazuron foi aplicado quando 70% dos capulhos estavam abertos, nas dosagens de 0, 45, 60 e 75 g ha-1; já o ethephon foi aplicado sete dias após o thidiazuron, quando já se observava desfolha de 85%, nas dosagens de 0, 960 e 1.440 g ha-1. O delineamento experimental utilizado foi o de blocos casualizados em faixa, com subparcelas subdivididas e quatro repetições. O cloreto de mepiquat proporcionou redução do número de frutos verdes, aumento do peso de 100 sementes e do peso médio de um capulho; a percentagem de desfolha aumentou com as dosagens de thidiazuron e ethephon; constatou-se que a interação cloreto de mepiquat x thidiazuron x ethephon foi significativa para percentagem de abertura de capulhos e produção de algodão em caroço.

Efeito da aplicação de baixa temperatura em plantas de macieira sobre o crescimento durante a aclimatização

Este trabalho objetivou avaliar o efeito da aplicação de baixa temperatura (4±1ºC) sobre o crescimento das brotações micropropagadas de um porta-enxerto de macieira (Malus prunifolia Borkh.), cv.Marubakaido, durante o processo de aclimatização. Durante as duas primeiras semanas de aclimatização, as plântulas foram transferidas para uma câmara de crescimento, e submetidas à temperatura de 4±1ºC por 0, 240, 480, 720, 960, 1.200 e 1.440 horas, sob fotoperíodo de 16 horas e radiação de 5µEm-2s-1. Em seguida, foram conduzidas para casa de vegetação e avaliadas por um período de 90 dias. Ao final do experimento, avaliou-se, ainda, o comprimento dos entrenós, o número de gemas e o peso da matéria seca da parte aérea e das raízes das plantas. A porcentagem de sobrevivência também foi avaliada após um mês de permanência das plantas em casa de vegetação. Houve aumento na altura das plantas e no comprimento dos entrenós, proporcional ao tempo de sua permanência sob baixa temperatura. O frio provocou decréscimo no peso seco das raízes, porém não afetou a sobrevivência das plantas, o número de gemas e o peso da matéria seca da parte aérea.

Lower Triassic bryozoan beds from Ellesmere Island, High Arctic, Canada

In the Sverdrup Basin (Canadian Arctic), the Lower Triassic Blind Fiord Formation, comprising siltstone and shale, overlies various Middle to Late Permian (post-Wordian) sedimentary units. This formation is subdivided into three members: the Confederation Point, Smith Creek and Svartfjeld members of, respectively, Griesbachian-Dienerian, Smithian-Spathian and Spathian ages. Lower Triassic bryozoan beds are known from many sections of Ellesmere Island, but have never been studied in detail. During the Early Triassic biotic recovery interval, immediately following the Permian/Triassic extinction event, only one new bryozoan genus evolved in the Boreal region: Arcticopora. The first lower Triassic bryozoan bed appears in the upper part of the Confederation Point Member, and is dated as late Dienerian. Succeeding bryozoan levels occur in the upper Smith Creek Member, and are late Smithian-early Spathian in age. Bryozoan beds occupy a similar stratigraphic position in Spitsbergen. There, they occur scattered in silt to coarse sandstone beds, but also in bryozoan-dominated packstone beds resembling the packstone units in the uppermost part of the Confederation Point Member of Ellesmere Island. Previously, bryozoan-rich beds of Triassic age have not been reported, and the present work fills an important time gap in the bryozoan carbonate database

Effect of supplementation with vitamin D3 and calcium on quantitative ultrasound of bone in elderly institutionalized women: a longitudinal study.

Supplementation of elderly institutionalized women with vitamin D and calcium decreased hip fractures and increased hip bone mineral density. Quantitative ultrasound (QUS) measurements can be performed in nursing homes, and easily repeated for follow-up. However, the effect of the correction of vitamin D deficiency on QUS parameters is not known. Therefore, 248 institutionalized women aged 62-98 years were included in a 2-year open controlled study. They were randomized into a treated group (n = 124), receiving 440 IU of vitamin D3 combined with 500 mg calcium (1250 mg calcium carbonate, Novartis) twice daily, and a control group (n = 124). One hundred and three women (42%), aged 84.5 +/- 7.5 years, completed the study: 50 in the treated group, 53 in the controls. QUS of the calcaneus, which measures BUA (broadband ultrasound attenuation) and SOS (speed of sound), and biochemical analysis were performed before and after 1 and 2 years of treatment. Only the results of the women with a complete follow-up were taken into account. Both groups had low initial mean serum 25-hydroxyvitamin D levels (11.9 +/- 1.2 and 11.7 +/- 1.2 micrograms/l; normal range 6.4-40.2 micrograms/l) and normal mean serum parathyroid hormone (PTH) levels (43.1 +/- 3.2 and 44.6 +/- 3.5 ng/l; normal range 10-70 ng/l, normal mean 31.8 +/- 2.3 ng/l). The treatment led to a correction of the metabolic disturbances, with an increase in 25-hydroxyvitamin D by 123% (p < 0.01) and a decrease in PTH by 18% (p < 0.05) and of alkaline phosphatase by 15% (p < 0.01). In the controls there was a worsening of the hypovitaminosis D, with a decrease of 25-hydroxyvitamin D by 51% (p < 0.01) and an increase in PTH by 51% (p < 0.01), while the serum calcium level decreased by only 2% (p < 0.01). After 2 years of treatment BUA increased significantly by 1.6% in the treated group (p < 0.05), and decreased by 2.3% in the controls (p < 0.01). Therefore, the difference in BUA between the treated subjects and the controls (3.9%) was significant after 2 years (p < 0.01). However, SOS decreased by the same amount in both groups (approximately 0.5%). In conclusion, BUA, but not SOS, reflected the positive effect on bone of supplementation with calcium and vitamin D3 in a population of elderly institutionalized women.

Brain Spectrins 240/235 and 240/235E: Differential Expression During Development of Chicken Dorsal Root Ganglia in vivo and in vitro.

Brain spectrin, a membrane-related cytoskeletal protein, exists as two isoforms. Brain spectrin 240/235 is localized preferentially in the perikaryon and axon of neuronal cells and brain spectrin 240/235E is found essentially in the neuronal soma and dendrites and in glia (Riederer et al., 1986, J. Cell Biol., 102, 2088 - 2097). The sensory neurons in dorsal root ganglia, devoid of any dendrites, make a good tool to investigate such differential expression of spectrin isoforms. In this study expression and localization of both brain spectrin isoforms were analysed during early chicken dorsal root ganglia development in vivo and in culture. Both isoforms appeared at embryonic day 6. Brain spectrin 240/235 exhibited a transient increase during embryonic development and was first expressed in ventrolateral neurons. In ganglion cells in situ and in culture this spectrin type showed a somato - axonal distribution pattern. In contrast, brain spectrin 240/235E slightly increased between E6 and E15 and remained practically unchanged. It was localized mainly in smaller neurons of the mediodorsal area as punctate staining in the cytoplasm, was restricted exclusively to the ganglion cell perikarya and was absent from axons both in situ and in culture. This study suggests that brain spectrin 240/235 may contribute towards outgrowth, elongation and maintenance of axonal processes and that brain spectrin 240/235E seems to be exclusively involved in the stabilization of the cytoarchitecture of cell bodies in a selected population of ganglion cells.

Olivine growth-rates in a tholeiitic basalt - an experimental study of melt inclusions in plagioclase

Basaltic glass inclusions trapped in plagioclase phenocrysts (An84) are remnant of their parent magmatic liquid. They can be used as natural reactors for the experimental investigation of olivine growth rate as a function of temperature. The growth of one olivine nucleus can be observed at constant temperature. Supercooling from 15-degrees to 150-degrees-C have been investigated. Growth habits vary from equant to feather in qualitative agreement with previous studies. Growth rates vary from < 10(-10) m s-1 to 6.10(-7) m s-1; they vary with the direction, the growth process (planar or dendritic) and the degree of supercooling. Chemical analysis of crystal overgrowth and the remaining liquid composition enables a mass-balance calculation which confirms the rates determined optically. The small number of results obtained so far does not permit to draw inferences on the growth mechanisms.

Criteria for the Evaluation and Disposition of Low-Traffic-Count Secondary Roads, HR-139, 1969

The State of Iowa has too many roads. Although ranking thirty-fourth in population, twenty-fifth in area, and twentieth in motor vehicle registration, it ranks seventh in the nation in miles of rural roads. In 1920 when Iowa's rural population was 1,528,000, there were 97,440 miles of secondary roads. In 1960 with rural population down 56 percent to 662,000, there were 91,000 miles of secondary roads--a 7 percent decrease. The question has been asked: "Who are these 'service roads' serving?" This excess mileage tends to dissipate road funds at a critical time of increasing public demand for better and safer roads.
