IPH response to DHSSPS and Food Standards Agency (NI) Front of Pack Labelling consultation

From 2016, it will be mandatory for most pre-packed food to carry nutrition labelling.  This provides an opportunity to review the provision of additional nutrition labelling that is provided voluntarily on the front of packs.  The Governments across the UK are committed to the provision of nutritional information to help consumers make better informed food choices. Key points from IPH response Obesity and related chronic conditions are already very prevalent and are expected to increase over the next decade, placing greater financial burden on health care services. Helping consumers to make informed choices about their diet is an important aspect of tackling obesity. Providing clear consistent and easy to understand front of pack (FoP) nutrition information is important in helping consumers to make healthy choices. IPH would support FoP nutrition information using the traffic light labelling scheme and High/Medium/Low text. FoP nutrition labelling should be supported by a public information campaign to educate consumers about portion sizes and recommended daily intakes of fat, sugar and salt. IPH would support a nutrition labelling approach which empowers and enables consumers to take responsibility for their own health through informed dietary choices. The FoP traffic light labelling scheme has the potential to encourage healthier product formulation as manufacturers pursue market share. This in turn would contribute to wider availability of healthier products.

Warm Front, Better Health: Health Impact Evaluation of the Warm Front Scheme

About 4 million households in the UK cannot adequately heat their homes in winter due to low income and poor quality housing, the two main causes of fuel poverty. The primary impact of fuel poverty is cold homes in winter which can lead to various health problems and even death among the vulnerable young and the elderly population. The government launched the Warm Front scheme in 2000 to tackle fuel poverty among the vulnerable households in England by providing energy efficiency measures in the forms insulation and modern heating system(??). By 2004, about 770,000 households had benefited from the Warm Front scheme and a total of 2 million households are still expected to benefit by 2010. Since 2001, the Bartlett has been investigating with London School of Hygiene & Tropical Medicine and Sheffield Hallam University, the health and the environmental impact of the Warm Front scheme. This investigative study is the most detailed to date on fuel poor dwellings based on detailed surveys of household and dwelling data, fuel consumption record and monitored temperature and relative humidity from 3,100 dwellings before and after the energy efficiency measures. The Warm Front investigation was expected to continue until the end of 2007. The findings from the investigation indicated that the Warm Front scheme was likely to have benefits in terms of improved thermal comfort and well-being as a result of mean temperature rise of 1.6C in the living room and 2.8C in the bedroom. Warm Front also lead to a decrease in indoor relative humidity mainly from the increased temperature since there appeared to be little impact on vapour pressure from changes in air tightness. Pressure test results indicated that the effects of air tightness measures such as draught stripping and cavity wall insulation were offset by the installation of a central heating system, particularly when the pipe work feeding radiators was installed below timber floors.

Clinicobiological progression and prognosis of oral squamous cell carcinoma in relation to the tumor invasive front: impact on prognosis

CONCLUSION: There are several factors that influence the final outcome when treating oral squamous cell carcinoma (OSCC). Invasive front phenomena and more importantly their clinicopathological translation can have a direct impact on survival, and subsequently on the decision for an adjuvant treatment. OBJECTIVES: In recent years, the concept of tumor-host interaction has been the subject of substantial efforts in cancer research. Tumoral behavior may be better understood when studying the changes occurring at the tumor-host interface. This study evaluated the influence of several clinicopathological features on the outcome of OSCCs. METHODS: The clinical records and pathology specimens of 54 patients with OSCC treated by primary resection were reviewed retrospectively. The pathologic features reviewed were: invasive front grading (IFG), stromal reaction, lymphovascular invasion (LVI), perineural invasion (PNI), margin status, and depth of invasion. RESULTS: High IFGs had a significant relationship with pT status and pN status. High IFGs were strongly correlated with nodal metastases (odds ratio (OR) = 4.77; confidence interaval (CI) = 1.37-16.64). Concerning survival, IFG had a strong impact on disease-free survival in patients treated unimodally, as did the depth of invasion in the same group. Lymphovascular involvement was found to have a negative impact on overall survival in patients treated multimodally.

Devolatilization-induced pressure build-up: Implications for reaction front movement and breccia pipe formation

Generation of fluids during metamorphism can significantly influence the fluid overpressure, and thus the fluid flow in metamorphic terrains. There is currently a large focus on developing numerical reactive transport models, and with it follows the need for analytical solutions to ensure correct numerical implementation. In this study, we derive both analytical and numerical solutions to reaction-induced fluid overpressure, coupled to temperature and fluid flow out of the reacting front. All equations are derived from basic principles of conservation of mass, energy and momentum. We focus on contact metamorphism, where devolatilization reactions are particularly important owing to high thermal fluxes allowing large volumes of fluids to be rapidly generated. The analytical solutions reveal three key factors involved in the pressure build-up: (i) The efficiency of the devolatilizing reaction front (pressure build-up) relative to fluid flow (pressure relaxation), (ii) the reaction temperature relative to the available heat in the system and (iii) the feedback of overpressure on the reaction temperature as a function of the Clapeyron slope. Finally, we apply the model to two geological case scenarios. In the first case, we investigate the influence of fluid overpressure on the movement of the reaction front and show that it can slow down significantly and may even be terminated owing to increased effective reaction temperature. In the second case, the model is applied to constrain the conditions for fracturing and inferred breccia pipe formation in organic-rich shales owing to methane generation in the contact aureole.

Analytical expressions for the flame front speed in the downward combustion of thin solid fuels and comparison to experiments

We derive analytical expressions for the propagation speed of downward combustion fronts of thin solid fuels with a background flow initially at rest. The classical combustion model for thin solid fuels that consists of five coupled reaction-convection-diffusion equations is here reduced into a single equation with the gas temperature as the single variable. For doing so we apply a two-zone combustion model that divides the system into a preheating region and a pyrolyzing region. The speed of the combustion front is obtained after matching the temperature and its derivative at the location that separates both regions.We also derive a simplified version of this analytical expression expected to be valid for a wide range of cases. Flame front velocities predicted by our analyticalexpressions agree well with experimental data found in the literature for a large variety of cases and substantially improve the results obtained from a previous well-known analytical expression

Speed of wave-front solutions to hyperbolic reaction-diffusion equations

The asymptotic speed problem of front solutions to hyperbolic reaction-diffusion (HRD) equations is studied in detail. We perform linear and variational analyses to obtain bounds for the speed. In contrast to what has been done in previous work, here we derive upper bounds in addition to lower ones in such a way that we can obtain improved bounds. For some functions it is possible to determine the speed without any uncertainty. This is also achieved for some systems of HRD (i.e., time-delayed Lotka-Volterra) equations that take into account the interaction among different species. An analytical analysis is performed for several systems of biological interest, and we find good agreement with the results of numerical simulations as well as with available observations for a system discussed recently

Front-Crawl propulsive phase detection using inertial sensors

Front crawl is an alternating swimming stroke technique in which different phases of arm movement induce changes in acceleration of limbs and body. This study proposes a new approach to use inertial body worn sensors to estimate main temporal phases of front crawl. Distinctive features in kinematic signals are used to detect the temporal phases. These temporal phases are key information sources of qualitative and quantitative evaluation of swimming coordination, which have been assessed previously by video analysis. The present method has been evaluated upon a wide range of coordination and showed a difference of 4.9% with video based system. The results are in line with video analysis inter-operator variability yet offering an easy-to-use system for trainers.

Feasibility and electromagnetic compatibility study of the ClearPEM front-end electronics for simultaneous PET-MR imaging

In this work we present a first feasibility study of the ClearPEM technology for simultaneous PET-MR imaging. The mutual electromagnetic interference (EMI) effects between both systems were evaluated on a 7 T magnet by characterizing the response behavior of the ClearPEM detectors and front-end electronics to pulsed RF power and switched magnetic field gradients; and by analyzing the MR system performance degradation from noise pickup into the RF receiver chain, and from magnetic susceptibility artifacts caused by PET front-end materials.
