When molecular oxygen accumulated in our atmosphere more than 2 billion years ago, aerobic organisms adapted using using oxygen as an electron acceptor in respiration. Although respiration is, by far, one of the most efficient ways of generating energy in biological systems, it has one harmful side-effect: incomplete reduction of dioxygen results in the formation of ROIs. § These include the su...

Unreported cases (SK Lee and AK Tanswell): case 1, boy of 25 weeks' gestation weighing 850 g; peak inspiratory/peak expiratory ventilator pressure (PIP/PEP) was 36/5 cm H20; he had pulmonary interstitial emphysema and arrhythmia. Case 2, girl of 27 weeks' gestation weighing 880 g; PIP/PEP was 34/4 cm H20; she had pulmonary interstitial emphysema, pneumothorax, and arrhythmia. Case 3, boy of 24 ...

The effects of five chemical agents on the stability, texture and microstructure of cooked comminuted meat batters were studied. ~-mercaptoethanol (/3-ME), hydrogen peroxide (H20~, ethylenediaminetetraacetic acid (EDT A), urea, and polyoxyetbylene sorbitan monooleate (fween 80) were used. The reduction of disulphide bonds by 8-ME or the oxidation of free sulphydryls by H20 2 prior to cooking di...

We examine factors controlling the photochemical oxidation of SO2 in tropospheric aerosols using a gas-aqueous photochemical model. Over a range of liquid water contents (3x10 -4g H20 m -3 to 9 g H20 m -3) and pH values (0 to 8), we find that H202(aq) and O3(aq) provide the major sinks for SO2 in the aqueous phase when pH is held constant at below 5 and larger than 6, respectively. OH(aq) may b...

An algorithm for calculating the scattering factors of atomic fragments in molecules as defined by the Stockholder recipe is presented. This method allows the calculation, from ab initio molecular wave functions, of structure factors including individual anisotropic atomic temperature factors. These structure factors agree with the model used in most leastsquares multipole-refinement procedures...

The article discusses Saul Kripke’s criticisms of the account reference general names he called “descriptivism” and considerations advanced in favour his own essentialist causal-historical natural kind terms. alternative conceptualism versus essentialism about terms is explained details. case made that most intuitions on which Kripke based arguments are highly controversial, main examples used ...

OBJECTIVE To analyze the benefit of voiding chain cystourethrography (VCC) [placing a radiographic opaque chain into the urethra and bladder and asking the patient to void under fluoroscopy] in the urodynamic evaluation of female bladder outlet obstruction (BOO). MATERIALS AND METHODS Females with post anti-incontinence operation voiding dysfunction who underwent urodynamic evaluation augment...

MSS. Intended for publication and books, etc., intended for review should be senit to Professer J. McKeen Cattell, Garrison. on-Hudson. N. Y. LIEBIG'S LAW OF THE MINIMUM IN RELATION TO GENERAL BIOLOGICAL PROBLEMS' TmE Law of the Minimum has never been accurately defined, although the idea that it involves is relatively simple. Professor B. E. Livingston says in a recent paper2 that "this prilnc...

The deformation behavior of capillary porous (CP) Ni and CP Ti is examined under uniaxial compression in air, water, ethanol. metals contained inert liquids such as H20 C2H5OH are used the heat pipes' active elements space applications. samples for mechanical testing were isostatic compacting vacuum annealing (porosity 60%). Uniaxial tests carried out ethanol Shimadzu AG-50K XD (traverse rate 0...
