abstract background: the current practice to measure rv is either by bpg or helium dilution methods which may not be available in all clinics due to their cost. methods: this paper outlines a method for both direct and indirect calculation of rv via pft with acceptable sensitivity (81 %, 60% ), specificity (71 %, 94%) and validity (76%, 78%) for obstructive and restrictive lung disease respecti...

This article introduces (and hopes to encourage thereby) the econometrics practitioner to (use) a homoscedasticity test referred to in the field of statistics as the modified Levene test. Econometrics orthodoxy (from University to practice level) has focused mainly on three heteroscedasticity tests, namely the Goldfeld-Quandt (GQ), Breusch-Pagan-Godfrey (BPG), and the White (W) test. The differ...

Globally, fish production in the wild is decreasing, and different aquaculture systems are presently being used for broodstock development captivity. Seasonally, raised captivity exhibit form of reproductive dysfunction at level brain-pituitary-gonad (BPG) axis. Primarily, vitellogenic completion final oocyte maturation inhibited females, males fail to spermiate spontaneously Reproductive dysfu...

The optical properties of a new family of neodymium doped BPG (Bi2O3-PbO-Ga2O3 ) glasses are presented. We measured a high refractive index, of 2.5, and a transmission cutoff in the far infrared at 8microm. Three intense emission bands are observed centered at 877nm, 1066nm and 1341nm. The emission cross-section is 10 -20 cm 2 and the total spectral linewidth is 30nm at 1066nm. The Judd-Ofelt p...

BACKGROUND Rheumatic heart disease (RHD) remains a major health concern for Aboriginal Australians. A key component of RHD control is prevention of recurrent acute rheumatic fever (ARF) using long-term secondary prophylaxis with intramuscular benzathine penicillin (BPG). This is the most important and cost-effective step in RHD control. However, there are significant challenges to effective imp...

A series of oxoperoxovanadium(V) complexes (ligands: H3nta ) nitrilotriacetic acid, H3heida ) N-(2hydroxyethyl)iminodiacetic acid, H2ada ) N-(2-amidomethyl)iminodiacetic acid, Hbpg ) N,N-bis(2-pyridylmethyl)glycine, and tpa ) N,N,N-tris(2-pyridylmethyl)amine) were characterized as functional models for the vanadium haloperoxidase enzymes. The crystal structures of K[VO(O2)Hheida], K[VO(O2)ada],...

Lossy compression of images corrupted by noise has several peculiarities. First, a specific filtering effect is observed. Second, optimal operation point (OOP) can be observed, i.e. such coder parameter (e.g., quantization step) value exist that quality compressed image calculated with respect to noise-free better compared uncompressed (original noisy) image. If OOP exists, it worth compressing...

Objectives: It has been known for almost a century that amyloidosis is frequently associated with chronic bacterial infection. Islet amyloid deposit is characteristic of type 2 diabetes. Periodontal disease, which is predominantly caused by several Gram negative bacteria, is a risk factor for type 2 diabetes. The goal of the study was to explore whether bacteria or their toxic components may pl...

OBJECTIVE This study aimed to compare the storage properties of red blood cell (RBC) concentrates of umbilical cordblood (UCB) and adult donor blood (ADB), and to evaluate the feasibility of UCB-RBC concentrate as an autologoussource for blood transfusion in very low birth weight (VLBW) preterm neonates. MATERIAL AND METHODS In all, 30 newborn (10 preterm, 20 full term) UCB and 31 ADB units w...

Abstract Time Projection Chambers (TPC)s are excellent tracking detectors for high multiplicity events and can intrinsically be high-rate, but limited by the ions created in their avalanche stage. GEMs Micromegas reduce IBF through geometry E͐ -field ratios, these lead to gain fluctuations still leave as dominant source of space charge. An active BPG block all ions, slow drift speed creates too ...
