Reducing the Adverse Effects of Transverse Cracking, HR-217, 1984

This research was initiated to identify methods of reducing the occurrence of transverse cracking. Eight (four repetitive) research sections were established to study three variations in the asphalt concrete pavement. The first variation was the comparison of low- and high-temperature-susceptible asphalt cement (AC) from two different sources. The second variable was to saw and seal transverse joints at spacings varying from 40 to 100 ft. The third variable was to increase the AC content in the asphalt treated base by 1 percent. The research sections were constructed with relatively few problems. Crack and joint surveys have been conducted on all research sections at intervals of less than 1 year since construction. No cracking was identified after the first winter season. The sawed joints also remained sealed through the first winter. At an age of approximately 1 1/2 years there was substantial cracking of the high-temperature-susceptible AC sections and substantial failure of the sealant material in the sawed joints. After almost 4 years, the asphalt pavement constructed with the high-temperature-susceptible AC produced a crack interval of 35 ft, the low-temperature-susceptible AC yielded an interval of 170 ft, and the low-temperature-susceptible AC with an increased AC content yielded an interval of 528 ft. The Pen-Vis number is an effective measure of temperature susceptibility of asphalt cements. The frequency of transverse cracking is affected by the temperature susceptibility of the AC. An increased AC content also reduces the frequency of transverse cracking.

Rosalía de Castro, sombra que se fai teoría

A figura auroral de Rosalía de Castro autorizou a aparición de novas poetas a finais do século XX mais, paradoxalmente, a partir da publicación dos seus libros fundacionais non xurdiu unha lexión de autoras que desde Cantares gallegos (1863) e Follas novas (1880) escribisen incesantemente a nación, ou simplemente, escribisen incesantemente en galego e tivesen por iso un recoñecemento canónico. Sen dúbida a intervención do patriarcadogaleguista provocou esa interrupción, que se entende mellor cando se teñenen conta os condicionantes socioliterarios que coutaban as mulleres escritoras (González Fernández, 2005: 15-19). Porque a finais do século XIX, e malia excepcións rechamantes, o pensamento hexemónicoconsideraba que as literatas eran unhas sabias ridículas, tal como sesancionara desde o coñecido capítulo V do Émile, ou l’Education (1762) deJean Jacques Rousseau en diante, aínda que houbese, por suposto, vocesdisidentes entre os seus contemporáneos, como Benito Jerónimo Feijoo noseu moi lido discurso XVI, Defensa de las mujeres, do seu Teatro crítico universal(1726). Nese sentido depreciativo do termo debe lerse o coñecido artigo deRosalía de Castro, Las literatas. Carta a Eduarda (1865).

A multicentre, retrospective case-control study assessing the role of trabecular bone score (TBS) in menopausal Caucasian women with low areal bone mineral density (BMDa): Analysing the odds of vertebral fracture.

INTRODUCTION: The trabecular bone score (TBS) is a new parameter that is determined from grey level analysis of DXA images. It relies on the mean thickness and volume fraction of trabecular bone microarchitecture. This was a preliminary case-control study to evaluate the potential diagnostic value of TBS, both alone and combined with bone mineral density (BMDa), in the assessment of vertebral fracture. METHODS: Out of a subject pool of 441 Caucasian, postmenopausal women between the ages of 50 and 80 years, we identified 42 women with osteoporosis-related vertebral fractures, and compared them with 126 age-matched women without any fractures (1 case: 3 controls). Primary outcomes were BMDa and TBS. Inter-group comparisons were undertaken using Student's t-tests and Wilcoxon signed ranks tests for parametric and non-parametric data, respectively. Odds ratios for vertebral fracture were calculated for each incremental one standard deviation decrease in BMDa and TBS, and areas under the receiver operating curve (AUC) calculated and sensitivity analysis were conducted to compare BMDa alone, TBS alone, and the combination of BMDa and TBS. Subgroup analyses were performed specifically for women with osteopenia, and for women with T-score-defined osteoporosis. RESULTS: Across all subjects (n=42, 126) weight and body mass index were greater and BMDa and TBS both less in women with fractures. The odds of vertebral fracture were 3.20 (95% CI, 2.01-5.08) for each incremental decrease in TBS, 1.95 (1.34-2.84) for BMDa, and 3.62 (2.32-5.65) for BMDa + TBS combined. The AUC was greater for TBS than for BMDa (0.746 vs. 0.662, p=0.011). At iso-specificity (61.9%) or iso-sensitivity (61.9%) for both BMDa and TBS, TBS + BMDa sensitivity or specificity was 19.1% or 16.7% greater than for either BMDa or TBS alone. Among subjects with osteoporosis (n=11, 40) both BMDa (p=0.0008) and TBS (p=0.0001) were lower in subjects with fractures, and both OR and AUC (p=0.013) for BMDa + TBS were greater than for BMDa alone (OR=4.04 [2.35-6.92] vs. 2.43 [1.49-3.95]; AUC=0.835 [0.755-0.897] vs. 0.718 [0.627-0.797], p=0.013). Among subjects with osteopenia, TBS was lower in women with fractures (p=0.0296), but BMDa was not (p=0.75). Similarly, the OR for TBS was statistically greater than 1.00 (2.82, 1.27-6.26), but not for BMDa (1.12, 0.56-2.22), as was the AUC (p=0.035), but there was no statistical difference in specificity (p=0.357) or sensitivity (p=0.678). CONCLUSIONS: The trabecular bone score warrants further study as to whether it has any clinical application in osteoporosis detection and the evaluation of fracture risk.

Tres argumentos para di/versificar as identidades de xénero: Arden, Pronomes e Lob*s

O noso propósito é presentar o proxecto máis ambicioso de poesía gai e lesbiana galega escrito, en paralelo, por Ana Romaní e Antón Lopo. A súa esculca poética representa unha interesante proposta de experimentación formal, na que se renova a concepción da poesía ó levala e adaptala a outros soportes, sen perder por iso a intensidade e a emoción lírica. Ademais ofrece dúas reflexións diferentes e complementarias sobre as identidades homosexuais, nas que se subliña o dereito a saír da sombra, a reivindicación do goce sexual (a arder e a ser lob*), e a definirse por posición e non pola imposición das convencións xenéricas (a rebeiión contra os pronomes).

Low environmental impact bleaching sequences for attaining high brightness level with eucalyptus SPP pulp

The alternatives used for minimizing the usage of chlorine dioxide in bleaching sequences included a hot acid hydrolysis (Ahot) stage, the use of hot chlorine dioxide (Dhot) and ozone stages at medium consistency and high consistency (Zmc and Zhc), in addition to stages with atmospheric hydrogen peroxide (P) and pressurized hydrogen peroxide (PO). The results were interpreted based on the cost of the chemical products, bleaching process yields and on minimizing the environmental impact of the bleaching process. In spite of some process restrictions, high ISO brightness levels were kept around 90 % brightness. Additionally, the inclusion of stages like acid hydrolysis, pressurized peroxide and ozone in the bleaching sequences provided an increase in operating flexibility, aimed at reducing environmental impact (ECF Light). The Dhot(EOP)D(PO) sequence presented lower operating cost for ISO brightness above 92 %. However, this kind of sequence was not allowed for closing the wastewater circuit, even partially. For ISO brightness level around 91%, the AhotZhcDP sequence presented a lower operating cost than the others

Deposição de agrotóxicos pulverizados na cultura da maçã

O objetivo deste trabalho foi avaliar a distribuição da deposição de agrotóxicos pulverizados em duas cultivares de maçã (Malus domestica Borkh). Uma calda com traçador Rodamina B foi pulverizada, com equipamento do tipo carreta com cortina de ar, com dois tipos de calibrações. Em uma calibração foram utilizados bicos cones JA-1, JA-2 e JA-3 e na outra, bicos leque AVI 110 ISO-04 e bicos JA-1. Não houve diferenças entre as calibrações, mas a deposição nas plantas foi decrescente da região apical para a basal. Nas calibrações testadas, 25% do traçador aplicado perdeu-se no solo.
