The Glauber method is extensively used to describe the motion of a hadronic projectile in interaction with the surrounding nuclear medium. One of the main approximations consists in the linearization of the wave equation for the interacting particle. We have studied the consequences of such an assumption in the case of the 12 C(e, e ′ p) 11 B * reaction at high proton momenta by comparing the r...

We point out that in a large class of superstring–inspired E(6) models, either an e+e− collider operating at a center–of–mass energy √ s = 1.5 TeV or higher must detect the pair production of charged or neutral exotic leptons, or an e+e− collider with √ s ≥ 300 GeV must discover at least one light neutral Higgs boson with invisible branching ratio exceeding 50%. If neither of these two signals ...

BACKGROUND Despite the rising health and safety concerns of e-cigarettes, a universal e-cigarette testing method is still in its early developmental stage. The aim of this study was to develop an e-liquid Reference Material that can be used to improve accuracy and reproducibility of research results, and advance health risk assessment of e-cigarette products. METHODS E-liquid Reference Materi...

SETTING Initial isolates should be tested for drug susceptibility to confirm the anticipated effectiveness of chemotherapy. OBJECTIVE To evaluate E-test strips for susceptibility testing of Mycobacterium tuberculosis. DESIGN A proportion method using Lowenstein-Jensen medium and the Bactec radiometric system were compared with the E-test (isoniazid [INH], rifampicin [RMP], ethambutol [EMB] ...

The validity of a photon shower generator QEDPS has been examined in detail. This is formulated based on the leading-logarithmic renormalization equation for the electron structure function and it provides a photon shower along the initial e ±. The main interest in the present work is to test the reliability of the generator to describe a process accompanying hard photons which are detected. Fo...

In e-testing it is important to administer tests composed of good quality question items. By the term “quality” we intend the potential of an item in effectively discriminating between strong and weak students and in obtaining tutor’s desired difficulty level. Since preparing items is a difficult and timeconsuming task, good items can be re-used for future tests. Among items with lower performa...

We have developed a new litmus paper test (DipTest) for detecting Escherichia coli (E. coli) in water samples by performing enzymatic reactions directly on the porous paper substrate. The paper strip consists of a long narrow piece of cellulose blotting paper coated with chemoattractant (at bottom edge), wax hydrophobic barrier (at the top edge), and custom formulated chemical reagents (at reac...
