Selected Markers of Inflammation in the Saliva of Children Infected with .

has been of interest to scientists and clinicians for many years, often causing diagnostic difficulties, especially in the youngest age group, in children. The presence of this bacterium in the population depends on the geographic region. However, it is assumed that even half of the world's population may be infected with .

The Influence of Basicity/Acidity of Lanthanum Systems on the Activity and Selectivity of the Transesterification Process.

The impact of heterogeneous catalytic systems, which are based on rare earth metals, on the properties of biodiesel produced via the transesterification process in a stationary reactor (autoclave) was thoroughly investigated. The physicochemical attributes, including the specific surface area, were analyzed employing the Brunauer-Emmett-Teller (BET) method. The basicity and acidity levels of the catalytic systems were evaluated through temperature-programmed desorption of ammonia and carbon dioxide (TPD-NH, TPD-CO), respectively.

Cracking Behavior and Deflections in Recycled-Aggregate Beams Reinforced with Waste Fibers Subjected to Long-Term Constant Loading.

This report presents the results of long-term tests on concrete beams reinforced with steel cord. In this study, natural aggregate was wholly replaced with waste sand or with wastes from the production of ceramic products and ceramic hollow bricks. The amounts of individual fractions used were determined in accordance with guidelines for reference concrete.

Comparative Analysis of Waste, Steel, and Polypropylene Microfibers as an Additive for Cement Mortar.

This study presents the results of laboratory experiments conducted to determine the mechanical parameters for cement mortar with various quantities of waste fibers, polypropylene microfibers, and steel microfibers. Waste fibers were used as samples and obtained using an end-of-life car tire recycling process. For comparison, samples with the addition of steel and polypropylene microfibers were tested.

Influence of Lanthanum Precursor on the Activity of Nickel Catalysts in the Mixed-Methane Reforming Process.

This work investigated the influence of the catalytic support precursor on the activity of nickel catalysts 20%Ni/5%LaO-95%AlO in the mixed methane reforming process. The activity tests were carried out at a temperature of 750 °C. The research showed that the catalyst prepared from the precursor containing chloride exhibited very low conversions of methane and carbon dioxide.

Effect of Ruthenium and Cerium Oxide (IV) Promotors on the Removal of Carbon Deposit Formed during the Mixed Methane Reforming Process.

This work investigates the effect of the addition of Ru and CeO on the process of gasification of carbon deposits formed on the surface of a nickel catalyst during the mixed methane reforming process. Activity studies of the mixed methane reforming process were carried out on (Ru)-Ni/CeO-AlO catalysts at the temperature of 650-750 °C. The ruthenium-promoted catalyst exhibited the highest activity.

Laboratory Investigation and Numerical Modelling of Concrete Reinforced with Recycled Steel Fibers.

In the last decades, fiber reinforced concrete have emerged as the possible key to revolutionize civil engineering. Among different types of fibers employed in concrete technology to date, the application of recycled steel fibers produced from end-of-life car tires appears to be a viable approach towards environmentally friendly construction. In this study, we demonstrate the laboratory research and numerical analysis of concrete reinforced with waste steel fibers recovered during the recycling process of end-of-life car tires.

The Effectiveness of Probiotic and Strains in Children with Atopic Dermatitis and Cow's Milk Protein Allergy: A Multicenter, Randomized, Double Blind, Placebo Controlled Study.

Probiotics seem to have promising effects in the prevention and treatment of allergic conditions including atopic dermatitis (AD) and food allergy. The purpose of this multicenter randomized placebo-controlled trial was to evaluate the effectiveness of a probiotic preparation comprising ŁOCK 0900, ŁOCK 0908, and ŁOCK 0918 in children under 2 years of age with AD and a cow's milk protein (CMP) allergy. The study enrolled 151 children, who-apart from being treated with a CMP elimination diet-were randomized to receive the probiotic preparation at a daily dose of 10 bacteria or a placebo for three months, with a subsequent nine-month follow-up.

Pneumonia: Still a serious disease in children.

Pneumocystis carinii pneumonia is a common opportunistic respiratory infection among children with human immunodeficiency virus and a weakened immune system. The primary infection in immunocompetent patients may be asymptomatic, whereas fever, shortness of breath, night sweats, nonproductive (dry) cough, pneumonia, progressive respiratory distress and apnea are cardinal symptoms of full-blown pneumocystis pneumonia. The diagnosis can be confirmed by histochemical staining of biological specimens or, recently, by polymerase chain reaction.

Deflection of Steel Fiber Reinforced Concrete Beams Based on Waste Sand.

The article describes the selected methods of calculating the deflection of steel fiber reinforced concrete beams. Additionally, the results of the study on the deflection of steel fiber reinforced concrete beams based on waste sand are presented. This paper compares deflections measured during the four point bending test of the steel fiber reinforced, waste sand fine aggregate concrete beam with values determined in accordance with Eurocode 2, the proposal of Tan, Paramasivam, and Tan, the modified method of Alsayed, Bywalski, and Kaminski, and Amin, Foster, and Kaufmann's method.
