Upconversion materials, a type of novel functional have manygood physicochemical properties, such as high luminescence stability, highchemical long luminous life, and low potential biotoxicity. How toregulate the upconversion materials is significant chal-lenge. Two-dimensional (2D) Van der Waals are new ofnanomaterials with layer structure. Some them capable quenchingthe dyes, which could be a...

Evaluating air transport service quality is fundamen-tal to ensure acceptable standards for users and improve the services offered passengers tourists. In transportation literature there a wide range of studies about evaluation public based on passengers’ perceptions; however, more recently, becoming relevant issue. in sector represents stimulating chal-lenge, given complexity system re-gards o...

Noninvasive cardiac imaging is a cornerstone of the diagnostic work-up in patients with suspected coronary artery disease (CAD), cardiomyopathy, heart failure, and congenital heart disease. It is essential for the assessment of CAD from functional and anatomical perspectives, and is considered the gate-keeper to invasive coronary angiography. Cardiac tests include exercise electrocardiography, ...

The role of cell-mediated protection to herpes simplex infection was studied in vivo and in vitro. Sensitized spleen cells, obtained from syngeneic mice immunized with herpes simplex virus, protected recipient mice against lethal chal lenge with herpes simplex virus. Survival was signifivantly greater in challenged mice that received washed spleen cells from donor animals immunized with herpes ...

lenge. Surgery can lead to iridodialysis, cyclodialysis, and subsequent bleeding [5]. The following steps prevented these complications in the two patients presented here. First, we used a modified Siepser technique for creation of the knot in situ. This type of knot minimizes the force pulling on the iris from the direction of the corneolimbal angle. Second, we used an IOL manipulator to creat...

3 Estimating the means and standard deviations of environmental data remains a great chal4 lenge because a substantial percentage of observations lies below or above detection limits. 5 The inadequacy of several common, ad hoc estimation procedures is clear; this study instead 6 proposes a robust moment estimation procedure for environmental data with a one-sided 7 detection limit. The procedur...

The subject of research in this paper are constructions with function verbs the German language legal profession (Funktionsverbgefüge – FVG) as a linguistic phenomenon that is culturally conditioned. authors strive to prove these structures represent chal- lenge understanding and translating texts from into Croatian. As complex structure whose verbal part has lost its original meaning, construc...

An attenuated live bluetongue virus (AL-BTV) serotype 8 vaccine of South African origin was evaluated for its ability to protect sheep against challenge with a European BTV-8 isolated from an outbreak. Two groups of sero-negative sheep were vaccinated with either a single or booster vaccination and challenged subcutaneously 28 days following vaccination. Groups of vaccinated challenged sheep sh...

BAKGRUNN Det er et politisk ønske at eldre personer med hjelpebehov skal kunne bo hjemme så lenge som mulig og motta helsetjenester utenfor institusjon. Denne gruppens grad av skrøpelighet samt risiko for akuttinnleggelser død, lite studert. Hensikten prosjektet var å studere dette gjennom to år i en middelsstor norsk kommune. MATERIALE OG METODE Et utvalg pasienter Sandefjord kommune, 65 eller...
