Background/Aims Fructose malabsorption (FM) mimics symptoms of irritable bowel syndrome (IBS), and its prevalence has increased. Diagnosing FM in IBS is challenging because of its overlap with small intestinal bacterial overgrowth (SIBO). We assessed the prevalence of FM by comparing patients with IBS with asymptomatic control individuals after excluding SIBO using the glucose hydrogen breath t...

This study investigated the removal of five selected non-phenolic trace organic contaminants (TrOC) by extracellular enzyme extract from a white-rot fungus. Except diclofenac, no other investigated non-phenolic TrOC were degraded by the extracellular enzyme extract. Improvement of enzymatic degradation of all TrOC was achieved in the presence of a redox mediator, namely, 1-hydroxybenzotriazole ...

A method of MC simulations including quantum interference, proposed recently by A.Krzywicki and the present author, is explained. 1. Introduction. The aim of this talk is to explain details of a scheme for MC simulations of multiparticle production including HBT interference which we proposed recently together with Andrzej Krzywicki [1]. The problem became suddenly of great practical importance...

Fig. 1. Cross-section of self-aligned base-emitter junction from Teledyne 500nm HBT process [6] InP-based transistor technologies, both high electron mobility transistors (HEMTs) and double heterojunction bipolar transistors (DHBTs), have demonstrated the highest reported transistor RF figures-of-merit. Both device technologies have been reported with current gain cutoff frequencies (ft) in exc...

In this paper, we report a new collector-up npn heterojunction bipolar transistor (C-up HBT) which employs a p-type doping buried layer inserted between extrinsic emitter and subemitter for current confinement. A theoretical study is performed to verify the functionality of the p-type doping buried layer using a two-dimensional device simulator. The structural parameters of the device and bias ...

With the exception of barley and rice, little is known about the existence of hemoglobins (Hbs) in cereals. This work reports the cloning and analysis of hb genes from maize (Zea mays ssp. mays) and teosinte (Zea mays ssp. parviglumis). Coding sequences of maize and teosinte hb genes (hbm and hbt, respectively) are highly similar to each other and are interrupted by three introns located at ide...

The efficacy of predeposited autologous blood transfusion (PABT) with and without intra/postoperative blood salvage to reduce or eliminate the need for homologous blood transfusion (HBT) in primary total hip or knee replacement surgery was investigated by retrospective and prospective studies. Depending on the type of surgery, one to three units of PABT eliminated the need for HBT in 50 to 78% ...

GaAs based Hetero-junction Bipolar Transistors (HBTs) have recently emerged as an important device technology for high speed and high frequency applications. The advantages of the HBTs fabricated on the new material systems are subjects of great interest and also studied by some of the researchers. The GaAs/AlGaAs device technology is ideally suited for such applications. In this work we are de...

We report on a possible application of the HBT phenomenon in testing the existence of two hypothetical phenomena. First, it is argued that the existence of a rapidly developing parton cascade in the earliest stages of a high energy nuclear collision process can be tested by studying two–photon HBT correlations over a wide longitudinal momentum scale – corresponding to the early photon emission ...

Hereditary benign telangiectasia (HBT), first described in 1971,1 is a rare autosomal dominant disorder.2' 3, 4 It is characterised by widespread telangiectases which may be punctate, plaquelike, radiating or merely a diffuse blush. The lesions generally are observed before adolescence, and rarely during the first year of life.5 It is important to recognise HBT as it may only cause cosmetic dis...
