Abstract:
Reduction in portion size, particularly for energy-dense foods, is increasingly addressed in healthy eating guidelines in a bid to tackle the obesity epidemic. The effect of portion size on other aspects of dietary quality, such as nutrient intakes, is less studied. The aim of the current work was to investigate associations between food portion sizes and key indicators of dietary quality, namely energy-adjusted intakes of saturated fat, dietary fibre, sodium, calcium, iron, folate and vitamin D, and dietary energy density (DED), in Irish adults on the days the foods were consumed.

We describe here five clinical HSV-2 isolates which were found to be unreactive to a panel of anti-gG-2 monoclonal antibodies and therefore considered phenotypically gG-2 negative. These isolates were further examined for expression of the secreted amino-terminal and cell-associated carboxy-terminal portions of gG-2 by immunoblott

The term "food-borne diseases" refers to illnesses contracted by ingesting contaminated food and includes both foodborne infections and foodborne intoxications. It is also frequently used interchangeably with "food poisoning." Approximately 3-5 billion episodes of diarrhea and over 1.8 million deaths in children under the age of five are estimated to occur globally, according to the WHO. A sizable portion of these incidents are attributed to consuming food, primarily food of animal origin contaminated with microbial pathogens or toxins.

A remarkable and frequent exception to this “usual” behavior is atmospheric blocking. Blocking occurs when the usual zonal flow is hindered by the establishment of a large-amplitude, quasi-stationary, high-pressure meridional circulation structure which “blocks” the flow of the westerlies and the progression of the atmospheric waves and disturbances embedded in them.

Abstract:
Negative R-ratio crack closure effects on Fatigue Crack Growth (FCG) are defined as the contribution of the compressive portion of the stress cycle to the crack extension, in addition to that contributed from the tensile portion of the cycle. Any potential decrease in FCG may be attributed to the mechanical effects of crack closure during the compressive part of the cycle. The overall effect is to decrease the crack opening portion of the stress range and to therefore reduce the crack growth rate compared to that obtained using the full stress range. This paper provides a brief overview of the

Abstract:
Abstract The cover of a cylindrical explosion containment vessel would suffer an extremely intense impact because the shock wave and blast products would converge at the cover area. To reduce the impact of shock waves to the cover, cases with aluminum foam placed at the end of the vessel and in the interior of the cylindrical portion are studied by numerical simulation and experiment. The result shows that aluminum foam located at the end of the vessel can have a great effect on the protection of the cover because it can absorb the energy of the shock wave that has spread to the end of the ves

&lt;p&gt;Cracking of concrete slab in the negative bending moment region of continuous composite girders is a key problem which needs to be solved in the design of continuous composite girder bridges. The main reason of concrete cracking in the negative bending moment region of continuous composite girder is tensile stress under the effects of temperature and load in the portion of integration. The paper gives the method of partial-combination to connect steel girder with concrete slab, that is, a rubber sleeve is placed on the stud of the negative bending moment region to increase the slip be

Abstract:
The foreign trade deficit of Kyrgyzstan is increasing year by year and the import is exceeding export about twice. A significant portion of the foreign trade deficit is covered by remittances. Furthermore, the ratio of remittance to Gross Domestic Product (GDP) is reached almost 30%. In this context, it is important to examine the effects of import, export and remittances to GDP. Empirical analysis using quarterly data covering the period 2000-2014 with ARDL Bounds Testing Approach showed that exports and imports effect GDP positively, while transfers from abroad effect negatively.

Parasitic power requirement is a key criterion in selection of suitable battery thermal management system (TMS) for EV applications. This paper presents a hybrid TMS with negative parasitic requirements, designed by integrating phase change material (PCM) with thermoelectric devices. The proposed system does not require any power consumption to maintain tight control over battery cell temperature during aggressive use and repetitive cycling. In addition, it can recover a portion of waste heat produced during the typical operation of EV battery packs. Commercially available LiFeP04 20 Ah pouch

Abstract:
Velocity vector fields around a falling sphere in a 1.0 wt % polyacrylamide (PAA) solution are obtained on a vertical cross section by particle image velocimetry (PIV). PAA solution is known as non-Newtonian fluid, which has shear thinning and viscoelastic property. Strain rate tensor fields and deformation fields are calculated from the velocity vector fields in order to visualize the dynamic behavior of the fluid quantitatively. In velocity vector field, two typical flow regions are observed in the wake of the sphere: approaching flow to the sphere, rising flow called “negative wake” [1]. Re

Abstract:
Liver biopsy images play a key role in the diagnosis of global non-alcoholic fatty liver disease (NAFLD). The NAFLD activity score (NAS) on liver biopsy images grades the amount of histological findings that reflect the progression of NAFLD. However, liver biopsy image analysis remains a challenging task due to its complex tissue structures and sparse distribution of histological findings. In this paper, we propose a sparse interpretable feature learning method (SparseX) to efficiently estimate NAS scores. First, we introduce an interpretable spatial sampling strategy based on histological fea

Abstract:
Financiers in early-stage entrepreneurial finance are known for their “spray-and-pray” approach, where they fund multiple start-ups expecting profits on a few to compensate losses on a lot of failed ones. We develop a theoretical framework in which financiers compete to fund entrepreneurs in an environment featuring risk, adverse selection, and limited liability. Financiers use steep payoff schedules to screen entrepreneurs, but limited liability implies they can only do so by giving more to all entrepreneurs. In equilibrium, competition for the best entrepreneurs forces intermediaries to offe

Our findings indicate a generally negative impact of out-of-field teaching in Math, Chemistry, and Physics on the likelihood of students taking the college entrance exam, while Biology's impact appears negligible, possibly due to its less intensive use of mathematics. Specifically, out-of-field teaching in these subjects decreases student's participation in the science portion of the college entra

The Montney Formation is a highly productive hydrocarbon reservoir with significant reserves of hydrocarbon gases and liquids making it of great economic importance to Canada. However, high concentrations of hydrogen sulfide (H2S) have been encountered during exploration and development that have detrimental effects on environmental, health, and economics of production. H2S is a highly toxic and corrosive gas and therefore it is essential to understand the distribution of H2S within the basin in order to enhance identification of areas with a high risk of encountering elevated H2S concentratio
