In vivo measurement of glycine with short echo-time 1H MRS in human brain at 7 T.

OBJECT: To determine whether glycine can be measured at 7 T in human brain with (1)H magnetic resonance spectroscopy (MRS). MATERIALS AND METHODS: The glycine singlet is overlapped by the larger signal of myo-inositol. Density matrix simulations were performed to determine the TE at which the myo-inositol signal was reduced the most, following a single spin-echo excitation. (1)H MRS was performed on an actively shielded 7 T scanner, in five healthy volunteers. RESULTS: At the TE of 30 ms, the myo-inositol signal intensity was substantially reduced. Quantification using LCModel yielded a glycine-to-creatine ratio of 0.14 +/- 0.01, with a Cramer-Rao lower bound (CRLB) of 7 +/- 1%. Furthermore, quantification of metabolites other than glycine was possible as well, with a CRLB mostly below 10%. CONCLUSION: It is possible to detect glycine at 7 T in human brain, at the short TE of 30 ms with a single spin-echo excitation scheme.

BRS 151 L-7: nova cultivar de amendoim para as condições do nordeste brasileiro

A BRS 151 L-7 é uma nova cultivar de amendoim, de sementes de coloração vermelha, de forma oblonga, desenvolvida pela Embrapa-Centro Nacional de Pesquisa de Algodão (CNPA), e destinada ao consumo in natura e à indústria de alimentos. A cultivar é de porte ereto, resultante do cruzamento entre a cultivar produtiva IAC-Tupã (tipo Valência) e a cultivar Senegal 55-437 (tipo Spanish), de ciclo curto. Em ensaios regionais realizados em 27 municípios de quatro estados da Região Nordeste, a cultivar apresentou grande potencial para produtividade de sementes, ciclo vegetativo de 87 dias, tolerância ao estresse hídrico, e grande adaptação ao cultivo em clima semi-árido. Sua produtividade média de vagens em condições experimentais é de 1.850 kg ha-1 em cultivo de sequeiro, e 4.500 kg ha-1 em condições irrigadas, o que corresponde a uma elevação na ordem de 12% e 38%, respectivamente, com relação à produtividade da cultivar tradicional Tatu. No aspecto nutricional, a cultivar BRS 151 L-7 tem baixo teor de óleo (46%), e sua farinha desengordurada contém 55% de proteína; entre os aminoácidos essenciais, é limitante apenas no teor de lisina, em comparação com o padrão da FAO/85.

Minimum VMA in HMA Based on Gradation and Volumetric Properties, MLR-95-7, 1996

The use of voids in the mineral aggregate (VMA) criteria for proper mix design of hot mix asphalt (HMA) mixtures is a time honored and fairly successful tool. Recent developments in the field of asphalt mix design have encouraged the use of mixtures with a coarse aggregate structure to resist the affect of heavy traffic loads. By using the equations presented, which account for both aggregate gradation and the volumetric properties of the materials, the mix designer is able to judge the proper VMA requirement for each unique blend of materials. By applying the new equations, the most economical mix may be selected without great risk of reduced durability. Supporting data from field application is presented to illustrate the use of the equations.

Blanket Curing to Promote Early Strength Concrete, MLR-87-7, 1989

Fast Track concrete has proven to be successful in obtaining high early strengths. This benefit does not come without cost. Special Type III cement and insulating blankets to accelerate the cure add to its expense when compared to conventional paving. This research was intended to determine the benefit derived from the use of insulating blankets to accelerate strength gain in three concrete mixes using Type I cement. The goal was to determine mixes and curing procedures that would result in a range of opening times. This determination would allow the most economical design for a particular project by tailoring it to a specific time restraint. Three mixes of various cement content were tested in the field. Flexural beams were cast for each mix and tested at various ages. Two test sections were placed for each mix, one section being cured with the addition of insulating blankets and the other being cured with only conventional curing compound. Iowa Department of Transportation specifications require 500 psi flexural strength before a pavement can be opened to traffic. Concrete with Fast Track proportions (nominal 7 1/2 bag), Type I cement, and insulating blankets reached that strength in approximately 36 hr, a standard mix (nominal 6 1/2 bag) using the blankets in approximately 48 hr, and the Fast Track proportions with Type I cement without blankets in about 60 hr. The results showed a significant improvement in early strength gain with the use of insulating blankets.

Investigation of high-resolution functional magnetic resonance imaging by means of surface and array radiofrequency coils at 7 T.

In this investigation, high-resolution, 1x1x1-mm(3) functional magnetic resonance imaging (fMRI) at 7 T is performed using a multichannel array head coil and a surface coil approach. Scan geometry was optimized for each coil separately to exploit the strengths of both coils. Acquisitions with the surface coil focused on partial brain coverage, while whole-brain coverage fMRI experiments were performed with the array head coil. BOLD sensitivity in the occipital lobe was found to be higher with the surface coil than with the head array, suggesting that restriction of signal detection to the area of interest may be beneficial for localized activation studies. Performing independent component analysis (ICA) decomposition of the fMRI data, we consistently detected BOLD signal changes and resting state networks. In the surface coil data, a small negative BOLD response could be detected in these resting state network areas. Also in the data acquired with the surface coil, two distinct components of the positive BOLD signal were consistently observed. These two components were tentatively assigned to tissue and venous signal changes.

Sprinkle Treatment of Asphalt Pavements, MLR-78-01, 1978

The paper reviews methods, materials, equipment and results to date of sprinkle treatment within the state. The Iowa Department of Transportation formerly the Iowa State Highway Commission, made its first attempts at sprinkle treatment of fresh asphalt concrete in 1974. Increased emphasis in mix design of asphalt mixes and aggregate selection of durable non-polishing materials has generated costly restrictions on the use of local materials. During the summer of 1975, a dual spinner, tail-gate spreader was mounted on a standard departmental dump truck to attempt additional sprinkle treatment on a section of Iowa 7 west of Ft. Dodge. The dump truck equipment was marginally satisfactory, but results of increased surface skid texture and durability were well demonstrated. On 1976 a new, current order dump truck was modified with an auxiliary transmission and a set of slick surfaced tires, and dual spinner spreader was mounted to again attempt surface sprinkle treatment, which was conducted in 1977.

CALOGÊNESE DE TECIDO FOLIAR DE PORTA-ENXERTO DE MACIEIRA M.7 (MALUS sp.) INDUZIDA POR BAP E CPPU

O trabalho foi conduzido com o objetivo de estudar a organogênese de macieira (Malus sp), após a obtenção de calo por meio de explantes de folhas do porta-enxerto M.7 multiplicado in vitro. O experimento foi conduzido no Laboratório de Cultura de Tecidos da Embrapa Clima Temperado, utilizando folhas com a superfície abaxial e adaxial em contato com o meio, com ou sem escarificação; associados às citocininas Benzilaminopurina (BAP) e Forchlorfenuron (CPPU) na concentração de 5mM. Utilizou-se o meio básico MS acrescido de sacarose (30 g.L-1 ), mio-inositol (100 mg.L-1) e ágar (6 g.L-1), além do regulador de crescimento Ácido Naftalenoácetico (ANA 0,5mM). Os tratamentos permaneceram por três semanas no escuro sob temperatura ambiente, o que propiciou 100% de formação de calos, sendo em seguida submetidos a fotoperíodo de 16 horas com intensidade luminosa de 20 mE.m-2.s-1 e temperatura de 25 ± 2ºC. Os explantes escarificados proporcionaram maior intensidade de calo do que a utilização de explantes intatos. Explantes escarificados com a superfície abaxial em contato com o meio proporcionaram maior intensidade de calo, independentemente de o meio conter BAP ou CPPU. O uso da escarificação, associado ao CPPU, promoveu uma maior intensidade de calo, independentemente da superfície do disco foliar. A superior regeneração de calos foi alcançada em condição de superfície abaxial do disco foliar associado ao CPPU. Portanto, o uso de explantes escarificados com a superfície abaxial em contato com o meio proporcionou aumento da intensidade de calo. O uso do explante escarificado em meio contendo CPPU proporcionou maior intensidade de calo, independentemente da superfície do disco foliar em contato com o meio.
