From diets to foods: Using linear programming to formulate a nutritious, minimum-cost porridge mix for children aged 1 to 2 years

Background. Linear programming has been used extensively as a tool for nutritional recommendations. Extending the methodology to food formulation presents new challenges, since not all combinations of nutritious ingredients will produce an acceptable food. Furthermore, it would help in implementation and in ensuring the feasibility of the suggested recommendations. Objective. To extend the previou

Broad-band multispectral microscope for imaging transmission spectroscopy employing an array of light-emitting diodes

Optical spectral analysis and multispectral imaging provide powerful means for characterizing samples in a wide variety of applications and on many spatial scales. We present a simple implementation of these techniques in the context of microscopy. A modified commercial microscope equipped with a CMOS imaging detector, combined with an array of light emitting diodes with emission ranging from ultr

Absorption and scattering of light from ensembles of randomly oriented aggregates

This paper presents one approach to the absorption and scattering of light from aggregates of primary particles. The primary particles are sphere like and small compared to the wavelength, whereas the aggregate can be large compared to the wavelength. This situation applies to when soot particles formed in flames are measured using methods based on laser light. The method presented in this work, c

How Long Does a Photoreceptor Cell Take to Die? Implications for the Causative Cell Death Mechanisms

The duration of cell death may allow deducing the underlying degenerative mechanism. To find out how long a photoreceptor takes to die, we used the rdl mouse model for retinal neurodegeneration, which is characterized by phosphodiesterase-6 (PDE6) dysfunction and photoreceptor death triggered by high cGMP levels. Based on cellular data on the progression of cGMP accumulation, cell death, and survi

Access to new sulfolene derivatives via formylation of thiolan-3-one

New tetrahydrothiophene derivatives, which are demonstrated to be reactive towards various nucleophiles and provide access to [b]- and [c]-fused sulfolenes are described. Application of heterocyclic sulfides as o-quinodimethane precursors is documented. (C) 2013 Elsevier Ltd. All rights reserved.

Sparse Chroma Estimation for Harmonic Audio

This work treats the estimation of the chromagram for harmonic audio signals using a block sparse reconstruction framework. Chroma has been used for decades as a key tool in audio analysis, and is typically formed using a Fourier-based framework that maps the fundamental frequency of a musical tone to its corresponding chroma. Such an approach often leads to problems with tone ambiguity, which we

The effect of temperature on the adiabatic laminar burning velocities of CH4-air and H-2-air flames

The effect of temperature on the adiabatic laminar burning velocities of CH4 + air and H-2 + air flames was analyzed. Available measurements were interpreted using correlation S-L = S-LO (T/T-o)(alpha). Particular attention was paid to the variation of the power exponent a with equivalence ratio at fixed ( atmospheric) pressure. Experimental data and proposed empirical expressions for a as a funct

Comparison of neuromuscular and quadriceps strengthening exercise in the treatment of varus malaligned knees with medial knee osteoarthritis: a randomised controlled trial protocol

Background: Osteoarthritis of the knee involving predominantly the medial tibiofemoral compartment is common in older people, giving rise to pain and loss of function. Many people experience progressive worsening of the disease over time, particularly those with varus malalignment and increased medial knee joint load. Therefore, interventions that can reduce excessive medial knee loading may be be

Tillfällig asyl skapar marginalisering

Permanent uppehållstillstånd är en förutsättning för att kunna planera ett liv. Det bör ges så fort som möjligt för att flyktingen ska kunna bygga en trygg framtid. En längre tids osäkerhet skapar marginalisering som är svår att bryta.

A 3-year Physical Activity Intervention Program Increases the Gain in Bone Mineral and Bone Width in Prepubertal Girls but not Boys: The Prospective Copenhagen School Child Interventions Study (CoSCIS)

The aim of this study was to evaluate the effect of increasing the amount of time spent in physical education classes on bone mineral accrual and gain in bone size in prepubertal Danish children. A total of 135 boys and 108 girls, aged 6-8 years, were included in a school-based curriculum intervention program where the usual time spent in physical education classes was doubled to four classes (180

Experimental investigation of the spin reorientation of Co/Au based magnetic nanodot arrays

(Co/Au) and (Au/ Co/ Au) nanomagnet arrays grown on nanostructured self-organized SiGe templates have been characterized by means of x-ray photoemission electron microscopy, x-ray magnetic circular dichroism, and by extended x-ray absorption spectroscopy using synchrotron radiation. In-plane magnetization is observed at room temperature for practically all Co thicknesses, a stable macroscopic perp

Quantification of left-to-right shunt through Patent Ductus Arteriosus by colour Doppler

Popular Abstract in Swedish Ductus arteriosus är ett kärl som finns hos foster för att styra blodet förbi lungorna. Kärlet stänger sig normalt inom 3 dagar efter födelsen men kan kvarstå öppet framför allt hos mycket för tidigt födda barn. Vid födelsen leder tryckförändringar i cirkulationen till att flödet i ductus vänder och blodet styrs istället till lungorna. Flödet genom ductus hos för tidigtThe aim of this thesis was to develop a non-invasive method to quantify the size of a shunt through a patent ductus arteriosus (PDA) by ultrasound and to test its usability in clinical settings. There is no consensus regarding the optimal management strategy for a PDA in premature infants. Non-steroidal anti-inflammatory drugs (NSAID) are the first treatment of choice. The use of NSAIDs, especiall

Synchrotron X-ray diffraction studies of LiMn2O4 and Li4Mn5O12 structures at high pressure

Experimental study of the phase transition in the lithium-excess lithium-manganese spinel over the pressure range 0-13 GPa has shown its suppression. This observation implies that the Li/Mn ratio, associated with the manganese oxidation state, plays an important role in the high-pressure phase transformation of the lithium-manganese spinels. As indicated by the results, the occupation of the octah
