Numerical analysis of ballistic imaging for revealing liquid breakup in dense sprays

This work demonstrates the capacity of a ballistic imaging instrument to suppress diffuse photons and improve image contrast, making it possible to view fluid structure in a spray where a fog of droplets occludes the near field. Analysis of the system is performed by means of a numerical system model. The model simulates light propagation and scattering in the measurement volume using a Monte Carl

Vaccines against atherosclerosis.

Atherosclerosis is the primary cause of acute myocardial infarction and stroke. It is well established that arterial inflammation in response to accumulation and oxidation of lipoproteins in the vascular wall is the major factor responsible for the development of atherosclerosis. During recent years, it has become apparent that this vascular inflammation is modulated by a complex array of autoimmu

Certainty and overconfidence in future preferences for food

We examine consumer certainty of future preferences and overconfidence in predicting future preferences. We explore how preference certainty and overconfidence impact the option value to revise today's decisions in the future. We design a laboratory experiment that creates a controlled choice environment, in which a subject's choice set (over food snacks) is known and constant over time, and the t

Combined Semilunar Valve Stenoses in Neonates: Management Approaches and Literature Review

Combination of right and left ventricular outflow tracts obstruction is extremely rare. Neonates with combined aortic stenosis (AS) and pulmonary stenosis (PS) present in critical condition and required urgent treatment. The management approach is not well defined. We report five female neonates with combined AS and PS presented to our institute in the last 5 years, age (1-18 days), weight (2.2-3.

Women’s Education, Empowerment, and Contraceptive Use in Sub-Saharan Africa: Findings from Recent Demographic and Health Surveys

Fertility remains higher and contraceptive levels are substantially lower in Sub-Saharan Africa than elsewhere in the developing world. In this paper we use information on individuals and couples provided in recent Demographic and Health Surveys (DHS, fifth wave) undertaken in Ghana, Kenya, Madagascar, and Zambia. We use bivariate and multivariate techniques to examine the determinants of contrace

Fundamental nonlinearities of the reactor-settler interaction in the activated sludge process

The activated sludge process can be modelled by ordinary and partial differential equations for the biological reactors and secondary settlers, respectively. Because of the complexity of such a system, simulation models are most often used to investigate them. However, simulation models cannot give general rules on how to control a complex nonlinear process. For a reduced-order model with only two

Psychological differences between early and late onset psoriasis: A study of personality traits, anxiety and depression in psoriasis.

BACKGROUND: Onset of psoriasis may occur at any age. Early negative experiences often influence personality development, and may lead to physical disease, anxiety and depression in adulthood. Knowledge about onset of psoriasis and psychopathology is limited. OBJECTIVES: To examine whether patients with early onset psoriasis differ psychologically from patients with late onset, regarding personalit

Men With Late Effects of Polio Decline More Than Women in Lower Limb Muscle Strength: A 4-Year Longitudinal Study.

In persons with prior paralytic poliomyelitis, progressive muscle weakness can occur after a stable period of at least 15 years. Knowledge is limited about which factors influence changes in lower limb muscle strength in these persons. Objective. To assess changes in lower limb muscle strength annually over 4 years in persons with late effects of polio and to identify prognostic factors for change

Effect of the addition of pigeon pea (Cajanus cajan) flour on the chemical, nutritional and sensory quality of cassava bread ("casabe")

Cassava bread ("casabe") is a product elaborated with grated and fermented pulp of bitter cassava, very popular in some Caribbean countries, rich in carbohydrates, low protein content and an acceptable level of cyanide. The goal of this research was to study the effect of the addition of pigeon pea flour (Cajanus cajan), as protein source, on the chemical, nutritional and sensory quality of cassav

Novel Loci Associated With PR Interval in a Genome-Wide Association Study of 10 African American Cohorts

Background-The PR interval, as measured by the resting, standard 12-lead ECG, reflects the duration of atrial/atrioventricular nodal depolarization. Substantial evidence exists for a genetic contribution to PR, including genome-wide association studies that have identified common genetic variants at 9 loci influencing PR in populations of European and Asian descent. However, few studies have exami

The Role of Phosphatidylinositol 3-Kinase Signaling Pathways in Pancreatic Cancer

Background: Pancreatic cancer is a highly malignant cancer and the fourth leading cause of cancer-related death. It is characterized by a rapid disease progression, a highly invasive tumor phenotype, and frequently resistance to chemotherapy. Despite significant advances in diagnosis, staging, and surgical management of the disease during the past decade, prognosis of pancreatic cancer is still di

Potential implications of future climate and land-cover changes for the fate and distribution of persistent organic pollutants in Europe

Aim Climate change is having far-reaching effects on the global environment. Here, the ALARM (Assessing Large-scale Risks for Biodiversity with Tested Methods, European Union 6th Framework Programme) climate change scenarios were used to assess changes to the fate of selected persistent organic pollutants (POPs). Scenarios detailing climate and land-cover changes, such as precipitation, temperatur

Crisis, austerity and opposition in mainstream media discourses of Greece

This article analyzes neoliberal articulations of the economic crisis in Greece, as they appear at the Ekathimerini daily. Neoliberalism is primarily understood as the ideology organizing the political strategies of late capitalist production. The analysis focuses on the ways the capitalist crisis is presented in the context of Greece, as well as the ways that socio-political opposition to neolibe

Migration and invasion of oral squamous carcinoma cells is promoted by WNT5A, a regulator of cancer progression.

Oral squamous cell carcinoma (OSCC) constitutes 90% of all cancers in the oral cavity, and the prognosis for patients diagnosed with OSCC is still poor. The identification of novel therapeutic targets and prognostic markers for OSCC is therefore essential. Previous studies of OSCC revealed an increased expression of WNT5A in the tumor tissue. However, no functional studies of WNT5A-induced effects

Healthy lifestyle and risk of breast cancer among postmenopausal women in the European Prospective Investigation into Cancer and Nutrition cohort study

Breast cancer is the most common cancer among women and prevention strategies are needed to reduce incidence worldwide. A healthy lifestyle index score (HLIS) was generated to investigate the joint effect of modifiable lifestyle factors on postmenopausal breast cancer risk. The study included 242,918 postmenopausal women from the multinational European Prospective Investigation into Cancer and Nut

Molecular mechanisms underlying deregulation of C/EBP alpha in acute myeloid leukemia

The CEBPA gene encodes a transcription factor protein that is crucial for granulocytic differentiation, regulation of myeloid gene expression and growth arrest. Mutations in one or both alleles of CEBPA are observed in about 10% of patients with acute myeloid leukemia (AML). Moreover, other genetic events associated with AML have been identified to deregulate C/EBP alpha expression and function at

Economic growth and the transition from traditional to modern energy in Sweden

We examine the role of substitution from traditional to modern energy carriers and of differential rates of innovation in the use of each of these in economic growth in Sweden from 1850 to 1950. We use a simple growth model with a nested CES production function and exogenous factor-augmenting technological change and carry out a counterfactual simulation based on the econometric results. Even thou
