Stripping gas is generally used to improve hydrogen yields in fermentations. Since CO2 is relatively easy to separate from hydrogen it could be an interesting stripping gas. However, a higher partial CO2 pressure is accompanied with an increased CO2 uptake in the liquid, where it hydrolyses and induces an increased requirement of NaOH to maintain the pH. This enhances the osmotic pressure in the c
A lysimeter method was evaluated for its suitability in gas emission studies by studying the effect of temperature on CO2 emissions (dark respiration) from cultivated peat soils. The study was carried out with organic soils from two locations in Sweden, a typical cultivated fen peat with low pH and high organic matter content (Orke) and a more uncommon fen peat with high pH and low organic matter
Background: Leptin resistance is considered a primary risk factor for obesity. It has been hypothesized that dietary cereal grain protein could cause leptin resistance by preventing leptin from binding to its receptor. Non-degraded dietary wheat protein has been found in human serum at a mean level of 41 ng/mL. Here, we report our findings from testing whether enzymatically digested gluten from wh
The dic(9;20)(p13.2;q11.2) is reported to be present in similar to 2% of childhood B-cell precursor acute lymphoblastic leukemia (BCP ALL). However, it easily escapes detection by G-banding analysis and its true prevalence is hence unknown. We performed interphase fluorescence in situ hybridization analyses-in a three-step manner-using probes for: (i) CDKN2A at 9p21, (ii) 20p and 20q subtelomeres
Exosomes are secreted nanovesicles that are able to transfer RNA and proteins to target cells. The emerging role of mesenchymal stem cell (MSC) exosomes as promoters of aerobic ATP synthesis restoration in damaged cells, prompted us to assess whether they contain an extramitochondrial aerobic respiration capacity. Exosomes were isolated from culture medium of human MSC from umbilical cord of ≥37-w
A study was undertaken to provide data on growth, feed conversion ratio (FCR) and faecal discharge of yellowtail kingfish (Seriola lalandi) fed three commercial diets used previously to culture this species in New Zealand. Fish were raised in tanks from 0.4 to 1.2 kg over the spring (water temperature 14–17°C) and summer (17–22°C) periods. There were considerable differences in volumetric and mass
The dryer fabric influences the mass and heat transfer, separating the hot, moist paper from the ambient drying air. A dynamic model is presented describing this mass and heat transfer in a dryer fabric based on the fabric parameters: effective diffusivity, porosity, tortuosity, calliper, effective permeability, thermal conductivity and basis weight. The model predicts moisture, temperature and pr
Ericsson India is looking into the possibility to enter a new business in the country. The business is a “telecom site leasing” service which would be included in Ericsson’s service portfolio. Services are an increasingly important part of the company’s total revenues. Demand for so called turn-key services, meaning full implementation and control over a customer’s network, is an example of a serv
The Single Molecule Spectroscopy Group at the department of Chemical Physics in the Chemical Centre of Lund University conducts research involving spectroscopy on single molecules of organic dyes. Fluorescence microscopy using a wide-field scheme has been used and such a scheme has many advantages such as full image capture at once when using a high sensitivity CCD or CMOS camera. Using different
Previous studies of stress and coping regarding urban bus drivers describe an unhealthy occupation in areas of psychological and physiological factors. In the present study a social constructionist approach was used to investigate Swedish urban bus drivers' constructs of stress and coping regarding passengers. Semi-structered interviews were performed with ten bus drivers, nine males and one f
Genom att infoga en material adverse change –klausul (”MAC”-klausul) i låneavtalet garanterar låntagaren att ingen väsentlig negativ förändring av dennes ekonomi inträffar under lånets löptid. Om en sådan förändring inträffar ges långivaren en rätt att säga upp lånet till förtida betalning. Uppsägning sker dock mycket sällan. Normalt används klausulen istället som ett påtryckningsmedel vid en omföBy inserting a material adverse change clause (a “MAC”- clause) into a loan agreement the borrower represents that no material adverse change in its economy will occur during the term of the loan. If such a change does occur, the lender is entitled to terminate the contract and require immediate repay-ment. Yet, MAC- clauses are rarely used to terminate a contract. Instead, the most common usage o
Popular Abstract in Swedish Polymerer och tensider är två mycket vanliga molekylslag som vi ofta stöter på i vårt vardagliga liv. Polymerer är extremt långa kedjor sammansatta av tusentals repeterande enheter. De förekommer både som hårda material (t ex plast) och i lösning (t ex målarfärg). Det finns syntetiska polymerer, såsom nylon och polyeten, och det finns biologiska polymerer, t ex cellulosA new approach to the study of aqueous mixtures of oppositely charged polymers and surfactants has been introduced. Pure polyion-surfactant ion complex salts have been synthesized and used as the point of departure. The elimination of the simple ions reduces the number of components in the mixtures, thus greatly simplifying the system. By mixing the complex salt with either the polyelectrolyte or
Employing high-resolution spectra obtained with the near-UV-sensitive detector on the Keck I HIRES, supplemented by data obtained with the McDonald Observatory 2d-coudé, we have performed a comprehensive chemical composition analysis of the bright r-process-rich metal-poor red giant star HD 221170. Analysis of 57 individual neutral and ionized species yielded abundances for a total of 46 elements
‘The Future of U.S. Public Diplomacy’ is a welcome addition to critical studies within the field of public diplomacy (PD) by public relations (PR) scholar Kathy Fitzpatrick. The monograph aims to untangle many of PD’s historical misconceptions and contribute to the development of its conceptual foundations through an examination of the U.S. experience. In truth, the interaction between the discuss
This paper presents a wideband quadrature radio receiver employing ΔΣ-based A/D-converting channel-select filters (ADCSFs). The output of the quadrature passive mixer is directly connected to the input of the ADCSFs, where a first-order ΔΣ modulator is incorporated into a fourth-order Butterworth channel-select filter (CSF) to provide sufficient dynamic range for a cellular system. A design method
BACKGROUND: Early life risk factors are associated with cardiometabolic disease, but have not been fully studied in atrial fibrillation (AF). There are discordant results from existing studies of birth weight and AF, and the impact of maternal body size, gestational age, placental size, and birth length is unknown.METHODS AND RESULTS: The Helsinki Birth Cohort Study includes 13 345 people born as
Aim: We aimed to study the feasibility and tolerability of a combination therapy consisting of glutamic acid decarboxylase (GAD-alum), Etanercept and vitamin D in children and adolescents with newly diagnosed with type 1 diabetes (T1D), and evaluate preservation of beta cell function. Material and Methods: Etanercept Diamyd Combination Regimen is an open-labelled multi-centre study pilot trial whi
