A novel approach to proton CT reconstruction using backprojection-then-filtering (BPF) is proposed. A list-mode algorithm is formulated accommodating non-linear proton paths. The analytical form is derived for the deblurring kernel necessary for the filtering step. Further, a finite matrix correction is derived to correct for the limited size of the backprojection matrix. High quantitative accu...

Physicochemical properties of banana peel flour (BPF) were studied in two varieties (Cavendish and Dream) and two stages of ripeness (green and ripe). BPF’s were analyzed for pH, total soluble solids (TSS), water holding capacity (WHC) at 40, 60 and 80C, oil holding capacity (OHC) at 40, 60 and 80C, colour values L, a and b, back extrusion force and viscosity, and the data were analyzed using...

The diagnosis and management of bronchopleural fistula (BPF) remain a major therapeutic challenge for clinicians. It is associated with significant morbidity and mortality. Diagnosis and localisation of BPF is sometimes difficult and may require multiple imaging and bronchoscopies. Successful management of a fistula is combined with treatment of the associated empyema cavity. The first step, th...

Activated carbon monoliths (ACMs) were fabricated by H2O activation using powdered fast pyrolytic char (PFPC) as a raw material and bio-oil phenol-formaldehyde (BPF) resin as a binder. The effects of the ratio of BPF resin to PFPC on textural and chemical-surface properties of the ACMs were investigated using elemental analysis, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (...

Synthesis, structure, and physical properties of a novel 11-methylbenzo[d]pyreno[4,5-b]furan (BPF) and its self-assembly in water have been reported. The performance of nanowire-based films in organic light-emitting diodes is much better than that of the thin film deposited by directly drop-coating BPF molecules in THF solution. SEM study indicates that the well-organized structure (nanowires) ...

Modern enterprises may be in need of developing the right application programs in a rapidly changing business environment for a fast time to market. However, most enterprises without a business process mechanism find it difficult to develop applications in time when they need to change their business. To solve this problem, we proposed a business process framework (BPF) based on closed architec...

In this paper, a novel compact band pass filter (BPF) is proposed for Global Positioning System (GPS) receivers. The proposed BPF configuration is composed of a low pass filter (LPF) section formed by the coupled line transformer connected with a radial stub and two short circuited stubs embedded within the 50Ω microstrip line connecting the input/output (I/O) port of LPF. The lumped equivalent...

All examined Haemophilus influenzae biogroup aegyptius isolates of the clone associated with Brazilian purpuric fever (the BPF clone) produced type 2 immunoglobulin A1 (IgA1) proteases encoded by identical iga genes that were distinct from the iga genes of other Brazilian H. influenzae biogroup aegyptius isolates. A partial nucleotide sequence analysis revealed close similarities to the iga gen...

We read with interest the paper by Bai et al. [1] regarding the efficacy of surgery, mainly pneumonectomies, in the treatment of tuberculosis (TB)-destroyed lungs and we congratulate them on their results. One of the most dreaded complications after pneumonectomy is the bronchopleural fistula (BPF), and this is particularly true for pneumonectomies performed for infectious diseases including TB...
