Abstract:

The work reported on is an extension of work done in Washington State to examine the systematic occurrence and variability in pavement mat density. The focus will be on the extent of the pavement that is affected by variable density due to temperature differentials and the fact that randomly based testing does not identify the occurrence of cyclic density differentials. Temperature differentials 14°C (25°F) or greater generally cannot be compacted to the same level of density as the surrounding mat and therefore lead to significant density differentials (increase in air voids of 2% or more).

Abstract:

Using extensive Canadian longitudinal data from the years 1969–71, the authors estimate union-nonunion wage differentials of 12–14 percent for 1969 and 13–16 percent for 1970. These estimates are not adjusted for selectivity because three different tests to identify selectivity yield no evidence of selectivity bias. The authors argue that although testing for selectivity is often essential, selectivity adjustments have resulted in greatly inflated estimates of union-nonunion wage differentials in some studies and should therefore be used with caution.

The number of M. grisea isolates from each field utilized for virulence testing varied from 28 to 47.

Abstract:

Mixed model methods allow genetic merit to be compared directly for pigs measured in different environments or generations. They take into account genetic relationships among all individuals in the population, and allow continuous selection throughout the animal's life. The advantage is more accurate selection in larger populations. The risk is that selection decisions are decentralised to many different sites, requiring a high degree of supervision.In 1986 a “group nucleus” using BLUP and AI was established for a pig dam line in order to improve both litter size and lean growth.

AbstractThe paper explores the determinants of yield differentials between sovereign bonds, using euro-area data. There is a common trend in yield differentials, which is correlated with a measure of aggregate risk. In contrast, liquidity differentials display sizeable heterogeneity and no common factor. We propose a simple model with endogenous liquidity demand, where a bond’s liquidity premium depends both on its transaction cost and on investment opportunities. The model predicts that yield differentials should increase in both liquidity and risk, with an interaction term of the opposite si

Suspension and cable-stayed bridge cables are currently vulnerable to multiple scenarios that can jeopardize the integrity of the bridge. These can include accidental truck fires and more recently, terrorist attacks. The inherent nature of suspension and cable-stay bridges leaves little redundancy to their structural loads paths. For this reason they are more susceptible to terrorist attacks than possibly any other structure.

Results indicate ineffective premiums/discounts and predictive bias. These results and the momentous changes taking place in the seafood industry are contrasted to discuss the viability of seafood f

Abstract:

Since 2008, 11 races of Phytophthora capsici have been identified in New Mexico based on their reactions to a set of host differentials, the New Mexico Recombinant Inbred Lines (NMRILs) developed by the Chile Pepper Breeding Program at New Mexico State University. The objective of this study was to appraise the current race structure of 13 isolates of P. capsici newly collected from chile pepper fields in New Mexico. Of the 13 isolates, 12 were identified as new races. Race 25 (isolate PWB175) was the most virulent isolate, and showed virulence that was higher than that of race 1 (PWB24), whic

Abstract:

PurposeThis paper attempts to explore possible contributing factors of females' outperformance and males' underperformance in the higher education in Pakistan from teachers' perspective. The central question of the study is what are the key factors that affect female and male students' educational performance at the university level? Using Artificial Neural Network (ANN) as a framework, we attempted to predict differentials of the perceived “female outperformance” and “male underperformance” in higher education. We carried out the study by employing quantitative research methods.Design/methodo

Abstract:

Complete blood cell counts (CBCs) are one of the most commonly ordered and informative blood tests in hospitals. The results from a CBC, which typically include white blood cell (WBC) counts with differentials, red blood cell (RBC) counts, platelet counts and hemoglobin measurements, can have implications for the diagnosis and screening of hundreds of diseases and treatments. Bulky and expensive hematology analyzers are currently used as a gold standard for acquiring CBCs. For nearly all CBCs performed today, the patient must travel to either a hospital with a large laboratory or to a centrali

Abstract:

Asthma is a heterogeneous disease differentiated by factors like allergen sensitivity, inflammation, sex, and age at onset. The mouse model is widely used to study the early-life development of allergic asthma. However, age-dependent allergen responses later in life remain relatively understudied and lack a widely accepted model. To differentiate age-dependent responses to the ubiquitous house dust mite (HDM), 3- and 9-mo-old female C57BL/6 mice were randomized into two groups each and exposed to HDM or phosphate-buffered saline (control) via intranasal instillation for sensitization and chall

Abstract:

The presence of Cladosporium fulvum (syn. Passalora fulva), causal agent of tomato leaf mold, was confirmed in the two main greenhouse-production areas for tomato in Argentina. Using both morphological characters and internal transcribed spacer sequencing, we confirmed the presence of physiological races of this pathogen. A diagnostic multiplex polymerase chain reaction (PCR) was also developed, using primers derived from C. fulvum avirulence (Avr) genes. In all, 20 isolates of Cladosporium spp. were obtained as monospore cultures and 12 were identified as C. fulvum. By this method, we showed

Abstract:

Annular seals are known to enhance rotordynamic stability margins and minimize vibration response levels in high-speed rotating machinery. Theoretical predictions for the rotordynamic characteristics of annular seals exist but additional experimental data is needed to properly anchor these results. NASA’s Marshall Space Flight Center (MSFC) has developed an annular seal test rig and facility to experimentally characterize axially fed annular seals. Annular seals with deliberately roughened stators (i.e., damping seals) have been shown analytically to increase stability margins of rocket engine

Abstract B-CLL, the most common type of leukemia in adults, is heterogeneous with a varying clinical course ranging from indolent to aggressive disease. CLL patients with mutated Ig V(H) genes have a good prognosis while those with non-mutated Ig V(H) status and expression of the ZAP70 protein tyrosine kinase generally have aggressive disease and shorter survival. Testing for IgV(H) mutations is not routinely performed due to cost and ZAP70 testing is still technically difficult. As these tests remain generally inappropriate for B-CLL patient screening, we tested the capacity of the new Beckma

Abstract:

The adaptive significance of temperature-dependent sex determination (TSD) remains elusive for many long-lived reptiles. Various hypotheses proposed potential ecological drivers of TSD. The Charnov-Bull’77 model remains the most robust and explains the maintenance of TSD in short-lived vertebrates, where sex ratios correlate with seasonal temperatures within years that confer sex-specific fitness (colder springs produce females who grow larger and gain in fecundity, whereas warmer summers produce males who mature at smaller size). Yet, evidence of fitness differentials correlated with incubati

Abstract:

A convolution approach to X-ray powder line-profile fitting is developed in which the line shape is synthesized from the Cu Kα emission profile, the dimensions of the diffractometer and the physical variables of the specimen. In addition to the integrated intensities and 2θ positions of the line profiles, the parameters that may be fitted include the receiving-slit width, the receiving-slit length, the X-ray-source size, the angle of divergence of the incident beam, the X-ray attenuation coefficient of the specimen and the crystallite size. This is a self-consistent approach to fitting as the
