Recent published and preliminary precision electroweak measurements are reviewed, including new results on the mass of the top quark and mass and width of the W boson. The experimental results are compared with the predictions of the Standard Model and are used to constrain its free parameters, notably the mass of the Higgs boson. The agreement between measurements and expectations from theory ...

Direct CP violation is studied in two pion decays of the neutral kaon. Using data collected in the first beam period in 1997, the result for the parameter Re (ε/ε) is (18.5 ± 4.5(stat) ± 5.8(syst))× 10−4. Talk presented at the EPS–HEP 99 Conference Tampere, Finland, July 15–21, 1999 a) On behalf of the NA48 Collaboration: Cagliari, Cambridge, CERN, Dubna, Edinburgh, Ferrara, Firenze, Mainz, Ors...

Many programs producing EPS graphics do not allow the inclusion of LATEX commands. While there exist several solutions to work around these difficulties, they all have various drawbacks. (See [1] for a discussion of several methods and an alternative approach to overcome these difficulties.) In this article, we will focus on a particular existing solution, the PSfrag package [2], which provides...

Recent developments in the measurement of precision electroweak measurements are summarised, notably new results on the mass of the top quark and mass and width of the W boson. Predictions of the Standard Model are compared to the experimental results which are used to constrain the input parameters of the Standard Model, in particular the mass of the Higgs boson. The agreement between measurem...

a new type of magnetically-recoverable catalyst was synthesized by the immobilization of h3pw12o40 on the surface of silica-encapsulated -fe2o3 nanoparticles. a series of novel 1,3,5-triaryl pyrazoline derivatives has been synthesized by the reaction of chalcone and phenylhydrazine in the presence of the -fe2o3@sio2-pw12nanoparticles,  in high yields. the structures of compounds obtained were...

backgrounds the degree of microleakage is one of the main criteria in evaluating the restorative materials such as glass ionomer (gi) restoratives, which are available in two forms: loose powder and liquid form to be hand-mixed or pre-proportioned in a capsule to be mixed mechanically. objectives this study was conducted to compare the microleakage of encapsulated gi restoratives with their han...

This study was conducted to investigate the effects of dietary inclusion of the encapsulated thyme essential oil (TEO), oregano essential oil (OEO) mixture and probiotic on growth performance, immune response and intestinal morphology of broiler chickens. A total of 490 one-day-old Ross 308 broiler chicks were randomly divided into seven treatments consisting of five replicates (n=14). Birds we...

objective: this study aimed to evaluate a co-encapsulated pegylated nano-liposome system based on two herbal anti-tumor drugs, silibinin and glycyrrhizic acid, for delivery to a hepatocellular carcinoma (hcc) cell line (hepg2). materials and methods: in this experimental study, co-encapsulated nano-liposomes by the thin layer film hydration method with hepes buffer and sonication at 60% amplitu...
