BACKGROUND Guatemala, as a party to the Framework Convention on Tobacco Control (FCTC), is required to regulate cigarette packaging and labeling and eliminate illicit tobacco trade. Current packaging and labeling characteristics (of legal and illegal cigarettes) and their compliance with the FCTC is unknown. METHODS We sought to analyze package and label characteristics of illegal and legal c...

We construct the set of all general (i.e. not necessarily rank 1) symmetric informationally complete (SIC) positive operator valued measures (POVMs), and thereby show that SIC-POVMs that are not necessarily rank 1 exist in any finite dimension d. In particular, we show that any orthonormal basis of a real vector space of dimension d 2 − 1 corresponds to some general SIC POVM and vice versa. Our...

Ceramic matrix composites (CMC’s), particularly silicon carbide (SiC) fiber-reinforced SiC-matrix (SiC/SiC) composites, have been studied for advanced nuclear energy applications for more than a decade. The perceived potentials for advanced SiC/SiC composites include the ability to operate at temperature regimes much higher than heat-resistant alloys, the inherent low inducedactivation nuclear ...

Abstract Chemical enhanced oil recovery (EOR) methods are shown to sweep the residual by altering physical properties of fluids after waterflooding improve recovery. This work presents an experimental study on surfactant/polymer injection for EOR in sandstone reservoirs. Interfacial tension measurements, emulsification and rheology tests performed select best candidates from thirteen commercial...

Silicon Carbide (SiC) is believed to be a revolutionary semiconductor material for power devices of the future; many SiC power devices have emerged as superior alternative power switch technology, especially in harsh environments with high temperature or high electric field. In this chapter, the challenges and recent develop‐ ments of SiC power devices are discussed. The first part is focused o...

Sand dripping in 1 dimensional Sand Pile Model is rst studied. Patterns and signals appear. Their behaviors and interactions are explained and asymptotic approximations are made. The total collapsing time of a single stack of sand is linear in function of the number of grains.

OBJECTIVES Commercial hospital discharge packs are commonly given to new mothers at the time of newborn hospital discharge. We evaluated the relationship between exclusive breastfeeding and the receipt of commercial hospital discharge packs in a population-based sample of Oregon women who initiated breastfeeding before newborn hospital discharge. METHODS We analyzed data from the 2000 and 200...

Conventional nasal packs, including BIPP (bismuth iodine paraffin paste), merocel or kaltostat are usually used to pack the nasal cavity while the coagulopathies are corrected. However, the coagulation profile can be rather difficult to correct in patients with haematological malignancies e.g. leukaemia. Thrombocytopenia or low platelet count is usually the commonest coagulopathy and can be res...

A good cooling inside a battery pack is important to avoid safety issues and avoid the development of too large internal temperature gradients. The temperature distributions inside two packs (in-line and staggered) made of large cylindrical lithium iron phosphate cells (of 18 Ah nominal capacity) are analysed in this paper during a 90 A constant discharge current. The analysis of the battery pa...
