Cohort study of art glass workers in Tuscany, Italy: mortality from non-malignant diseases. (1/1409)

This investigation studies cause-specific mortality of art glass workers employed in 17 industrial facilities in Tuscany, Italy. A cohort of 3,390 workers employed for at least 1 year was enumerated from company payrolls. Follow-up was between the start of employment in each factory and 31 December 1993. The cause-specific expected mortality was computed relative to Tuscany rates and specified for gender, 5-year age groups and calendar year. Separate analyses were carried out for the jobs of makers and formers and for batch mixers. Among males (3, 180 individuals) observed mortality for non-cancer causes was higher than expected for hypertensive disease [standardized mortality ratio (SMR) = 178, 90% confidence interval (90% CI) = 96-301], pneumoconiosis (SMR = 200, 90% CI = 94-376) and diseases of the genitourinary system (SMR = 169, 90% CI = 95-279). Increases for the above causes were shown also among makers and formers: hypertensive disease (SMR = 182, 90% CI = 85-341), pneumoconiosis (SMR = 250, 90% CI = 109-493) and diseases of the genitourinary system (SMR = 224, 90% CI = 121-380). For batch mixers an increase was present for cerebrovascular disease. The observed mortality for cancer causes was above the expected for cancers of the larynx, lung, stomach and brain. This study points to the existence for Tuscan glass workers of health effects in addition to cancer; previously observed carcinogenic effects were also confirmed.  (+info)

Respiratory symptoms among glass bottle workers--cough and airways irritancy syndrome? (2/1409)

Glass bottle workers have been shown to experience an excess of respiratory symptoms. This work describes in detail the symptoms reported by a cohort of 69 symptomatic glass bottle workers. Symptoms, employment history and clinical investigations including radiology, spirometry and serial peak expiratory flow rate records were retrospectively analyzed from clinical records. The results showed a consistent syndrome of work-related eye, nose and throat irritation followed after a variable period by shortness of breath. The latent interval between starting work and first developing symptoms was typically 4 years (median = 4 yrs; range = 0-28). The interval preceding the development of dysponea was longer and much more variable (median = 16 yrs; range = 3-40). Spirometry was not markedly abnormal in the group but 57% of workers had abnormal serial peak expiratory flow rate charts. Workers in this industry experience upper and lower respiratory tract symptoms consistent with irritant exposure. The long-term functional significance of these symptoms should be formally investigated.  (+info)

Hierarchical cluster analysis applied to workers' exposures in fiberglass insulation manufacturing. (3/1409)

The objectives of this study were to explore the application of cluster analysis to the characterization of multiple exposures in industrial hygiene practice and to compare exposure groupings based on the result from cluster analysis with that based on non-measurement-based approaches commonly used in epidemiology. Cluster analysis was performed for 37 workers simultaneously exposed to three agents (endotoxin, phenolic compounds and formaldehyde) in fiberglass insulation manufacturing. Different clustering algorithms, including complete-linkage (or farthest-neighbor), single-linkage (or nearest-neighbor), group-average and model-based clustering approaches, were used to construct the tree structures from which clusters can be formed. Differences were observed between the exposure clusters constructed by these different clustering algorithms. When contrasting the exposure classification based on tree structures with that based on non-measurement-based information, the results indicate that the exposure clusters identified from the tree structures had little in common with the classification results from either the traditional exposure zone or the work group classification approach. In terms of the defining homogeneous exposure groups or from the standpoint of health risk, some toxicological normalization in the components of the exposure vector appears to be required in order to form meaningful exposure groupings from cluster analysis. Finally, it remains important to see if the lack of correspondence between exposure groups based on epidemiological classification and measurement data is a peculiarity of the data or a more general problem in multivariate exposure analysis.  (+info)

The induction of macrophage spreading: role of coagulation factors and the complement system. (4/1409)

Unstimulated mouse peritoneal macrophages, attached to either glass or plastic substrates, responded to factors generated in serum and plasma by spreading and increasing their apparent surface area up to eightfold. Two distinct and dissociable systems were involved. The first appears related to the distinct and dissociable systems were involved. The first appears related to the contact phase of blood coagulation. It is activated by glass and not plastic surfaces, depleted by kaolin adsorption, and inhibited by soybean trypsin inhibitor. In contrast, a separate complement-dependent system can be generated in kaolin-adsorbed plasma. Activation of the complement system can occur either by the alternate or classical pathways and generates a relatively small effector molecule which is dialyzable. These factors presumably influencing the surface membrane and underlying structures may explain the rapid spreading of activated macrophages observed after both infections and chemical peritoneal inflammatory agents.  (+info)

Multiple oligodeoxyribonucleotide syntheseson a reusable solid-phase CPG support via the hydroquinone-O,O'-diacetic acid (Q-Linker) linker arm. (5/1409)

A strategy for oligodeoxyribonucleotide synthesis on a reusable CPG solid-phase support, derivatized with hydroxyl groups instead of amino groups, has been developed. Ester linkages, through a base labile hydroquinone- O, O '-diacetic acid ( Q-Linker ) linker arm, were used to couple the first nucleoside to the hydroxyl groups on the support. This coupling was rapidly accomplished (10 min) using O -benzotriazol-1-yl- N, N, N ', N '-tetramethyluronium hexafluorophosphate (HBTU) and 1-hydroxybenzotriazole as the activating reagents. Oligodeoxyribonucleotide synthesis was performed using existing procedures and reagents, except a more labile capping reagent, such as chloro-acetic anhydride, methoxyacetic anhydride or t-butylphenoxyacetic anhydride, was used instead of acetic anhydride. After each oligodeoxyribonucleotide synthesis, the product was cleaved from the support with ammonium hydroxide (3 min) and deprotected as usual. Residual linker arms or capping groups were removed by treatment with ammonium hydroxide/methylamine reagent and the regenerated support was capable of reuse. Up to six different oligodeoxyribonucleotide syntheses or up to 25 cycles of nucleoside derivatization and cleavage were consecutively performed on the reusable support. This method may provide a significant cost advantage over conventional single-use solid supports currently used for the manufacture of antisense oligodeoxyribonucleotides.  (+info)

Bacteriophage inactivation at the air-water-solid interface in dynamic batch systems. (6/1409)

Bacteriophages have been widely used as surrogates for human enteric viruses in many studies on virus transport and fate. In this investigation, the fates of three bacteriophages, MS2, R17, and phiX174, were studied in a series of dynamic batch experiments. Both MS2 and R17 readily underwent inactivation in batch experiments where solutions of each phage were percolated through tubes packed with varying ratios of glass and Teflon beads. MS2 and R17 inactivation was the result of exposure to destructive forces at the dynamic air-water-solid interface. phiX174, however, did not undergo inactivation in similar studies, suggesting that this phage does not accumulate at air-water interfaces or is not affected by interfacial forces in the same manner. Other batch experiments showed that MS2 and R17 were increasingly inactivated during mixing in polypropylene tubes as the ionic strength of the solution was raised (phiX174 was not affected). By the addition of Tween 80 to suspensions of MS2 and R17, phage inactivation was prevented. Our data suggest that viral inactivation in simple dynamic batch experiments is dependent upon (i) the presence of a dynamic air-water-solid interface (where the solid is a hydrophobic surface), (ii) the ionic strength of the solution, (iii) the concentration of surface active compounds in the solution, and (iv) the type of virus used.  (+info)

Critical role of glass fiber length in TNF-alpha production and transcription factor activation in macrophages. (7/1409)

Recent studies have demonstrated that dielectrophoresis is an efficient method for the separation of fibers according to fiber length. This method allows the investigation of fiber-cell interactions with fiber samples of the same composition but of different lengths. In the present study, we analyzed the effects of length on the interaction between glass fibers and macrophages by focusing on production of the inflammatory cytokine tumor necrosis factor (TNF)-alpha in a mouse macrophage cell line (RAW 264.7). The underlying molecular mechanisms controlling TNF-alpha production were investigated at the gene transcription level. The results show that glass fibers induced TNF-alpha production in macrophages and that this induction was associated with activation of the gene promoter. Activation of the transcription factor nuclear factor (NF)-kappaB was responsible for this induced promoter activity. The inhibition of both TNF-alpha production and NF-kappaB activation by N-acetyl-L-cysteine, an antioxidant, indicates that generation of oxidants may contribute to the induction of this cytokine and activation of this transcription factor by glass fibers. Long fibers (17 micrometer) were significantly more potent than short fibers (7 micrometer) in inducing NF-kappaB activation, the gene promoter activity, and the production of TNF-alpha. This fiber length-dependent difference in the stimulatory potency correlated with the fact that macrophages were able to completely engulf short glass fibers, whereas phagocytosis of long glass fibers was incomplete. These results suggest that fiber length plays a critical role in the potential pathogenicity of glass fibers.  (+info)

Stability of gentamicin in serum. (8/1409)

Patients' sera were divided into three portions when the initial gentamicin level was determined and were stored at -20, 4, and 25 degrees C in plastic or glass tubes. Gentamicin levels were repeated after 1 and 2 days of storage at the respective temperatures. There was no significant difference in gentamicin levels among portions, except those from a patient in renal failure with high serum concentrations of carbenicillin.  (+info)

LONDON - Borosilicate glass is a kind of glass containing such main glass-forming constituents as boron trioxide and silica. Borosilicate glasses are widely recognized for having low coefficients of thermal expansion, which makes them resistant to thermal shock much more than any other common glass. Borosilicate glass finds numerous applications, for instance in healthcare, electronics, cookware, lightning, optics industries, among others.. Shandong Yaohua, Schott, Sunshore, JiangSu YuanSheng, MAXOS, Changzhou Tianxiang, Kimble, Hanzhong Xinhai, Corning, REFMEX GL, Kavalier, NEG, Shandong Linuo, Jiangsu Sunrain and Huailai Tianyuan are among the top players in the industry..

Back in March 2018 Lorraine Finch, a photograph conservator, gave the archive team some valuable training on identifying different photographic processes and how to care for the different types of photographic material. We were aware that among the various photographic formats held in the Jesuits in Britain Archives there was a collection of glass plate negatives.. Before cellulose nitrate film was invented in 1903, photographic emulsions were made on glass supports, more typically known as glass plate negatives, and this enabled amateur as well as professional photography to flourish. There are two separate glass plate negative photographic methods which both consist of a light sensitive emulsion fixed to the glass plate base with a binder. In 1851, at almost the same time, Frederick Scott Archer (1813-1857) and Jean-Baptiste Gustave Le Gray (1820-1884) produced the first collodion wet plate negatives. Wet plate negatives were produced by spreading a glass plate with collodion, bathed in silver ...

Bioresorbable (or bioabsorbable) metallic glass is a type of amorphous metal, which is based on the Mg-Zn-Ca ternary system. Containing only elements which already exist inside the human body, namely Mg, Zn and Ca, these amorphous alloys are a special type of biodegradable metal. The first reported metallic glass was an alloy (Au75Si25) produced at Caltech by W. Klement (Jr.), Willens and Duwez in 1960. This and other early glass-forming alloys had to be cooled extremely rapidly (in the order of one mega-kelvin per second, 106 K/s) to avoid crystallization. An important consequence of this was that metallic glasses could only be produced in a limited number of forms (typically ribbons, foils, or wires) in which one or more dimensions were small so that heat could be extracted quickly enough to achieve the necessary cooling rates. As a result, metallic glass specimens (with a few exceptions) were limited to thicknesses of less than one hundred micrometers. Mg-Zn-Ca based metallic glasses are a ...

The effects of the addition of divalent metal oxides on the structure and thermophysical properties of the mixed alkali borosilicate glass system used for high level radioactive waste immobilisation have been studied. Densities, molar volumes, linear thermal expansivities and glass transition temperatures are reported and structural information has been obtained using B-11 and Si-29 magic angle spinning (MAS) NMR. Molar volume is controlled by ion size and by the formation of network polyhedra, whilst thermal expansion reflects the network rigidity. Changes in the glass transition temperature, T-S, are consistent with the different values of the heat of formation of the oxides added. Alkaline earth oxides produce an initial increase in the fraction of 4-coordinated boron, N-4, whereas PbO and ZnO reduce N-4. Si-29 NMR of the alkaline earth oxide glasses shows the presence of significant concentrations of nonbridging oxygens, consistent with a previous study of the aqueous corrosion behaviour of ...

Following the success of bioactive glass in orthopaedic applications, bioactive glass was adopted for use in dentistry applications. It has shown substantial benefit in the repair of periodontal defects.4 The observed antimicrobial activity alongside its demonstrated high strength made bioactive glass a prime candidate for tooth fillings. Fillings made with bioactive glass should slow secondary tooth decay by inhibiting bacterial colonization and increase the durability of composite filling materials. Furthermore, it was hypothesized that the bioactive glass may also provide minerals to strengthen the damaged surface of the tooth.. Evaluations of bioactive glass as a tooth filling have recently shown that such extrapolations to dentistry are indeed correct. Studies have demonstrated that the addition of bioactive glass to dental filling materials enhanced mineral formation in the dentin, promoting remineralization of dental caries7 and improved the mechanical properties of a filling in an ...

Glass transition and crystallization behavior of several Mg-Ni-Nd metallic glasses has been systematically studied by temperature-modulated differential scanning calorimetry (TMDSC). The glass transition transformation of alloys Mg75Ni10Nd15 and Mg77Ni 18Ni5, which cannot be detected in conventional differential scanning calorimetry (DSC) heating scans, was observed through TMDSC measurements. It was concluded that the signal of the glass transition on the DSC scans overlapped with the relatively large heat release from the primary crystallization of either intermetallic Mg3Nd phase in glassy Mg75Ni10Nd15 alloy or Mg2Ni phase in amorphous alloy Mg77Ni18Ni5. Increasing the content of Ni in alloy Mg75Ni10Nd 15 can suppress the precipitation processes of Mg3Nd, and results in the appearance of glass transition transformation on DSC heating curves. This confirmed and verified our TMDSC measurements. Clear observation of glass transition and understanding of crystallization micro-mechanism in such ...

The aim of the present work is to investigate the effect of substituting B2O3 for Al2O3 in a nonstoichiometric lithium disilicate (Li2Si2O5, LS2) glass composition belonging to the system Li2O-K2O-Al2O3-SiO2. Addition of equimolar amounts of K2O and Al2O3 to binary lithium silicate glass compositions improves chemical resistance, sintering behaviour and mechanical properties of the glassceramics produced from sintered glass powder compacts. However, in bulk (monolithic) glasses Al2O3 addition hinders bulk nucleation. It also suppresses crystallization of LS2 and promotes formation of a meta-stable crystalline phase called lithium metasilicate (Li2SiO3, LS). The results showed that B substitution resulted in the depolymerisation of the glass network increasing the percentage of NBOs leading to decreasing viscosity, molar volumes, oxygen densities and glass transition temperatures. The simultaneous addition of Al and B into the glass composition resulted in decreased liquid-liquid phase segregation (LLPS)

The structural behavior of a new connection design, the embedded adhesive connection, used for laminated glass plates is investigated. The connection consists of an aluminum plate encapsulated in-between two adjacent triple layered laminated glass plates. Fastening between glass and aluminum is ensured using a structural adhesive. At first, the elastic and viscoelastic material properties of the adhesive are identified where the influence of load-rate and failure properties are also examined. Through an inverse analysis using the finite element method, the experimental observations are replicated to identify a material model of the adhesive. The material model consists of an elastic and linear viscoelastic formulation suitable for a numerical implementation of the material. Based on two relevant load cases, out-of-plane bending and in-plane shear, the connection performance is investigated both for short and long-term durations. Using the finite element method, the connection experiments are ...
Metallic glasses represent one kind of advanced material, very popular in recent decades. These materials are very adaptable like plastics for their manufacturability in very complex shapes. TPF (Thermoplastic forming) based processes seem very good method to process them. These materials can compete with plastics but have metallic properties. They behave as magnetic materials with less hysteresis loss and less eddy current loss making them suitable for transformer and MEMS (Micro-Electromechanical System) applications. These materials exhibit good corrosion resistance, hardness and toughness. Based on the property and application, metallic glasses are good rivals to plastics, metals and ceramics. Chemical composition and kinetics of supercooling of these materials are the areas where young researchers can focus attention with a view to their improvement.
Density, elastic modulus and the pair distribution function of Co-Fe-Ta-B metallic glasses were obtained by ab-initio molecular dynamics simulations and measured for sputtered thin films using X-ray reflectivity, nanoindentation and X-ray diffraction using high energy photons. The computationally obtained density of 8.19 g/cm3 for Co43Fe20Ta5.5B31.5 and 8.42 g/cm3 for Co45.5Fe24Ta6B24.5, as well as the Youngs moduli of 273 and 251 GPa, respectively, are consistent with our experiments and literature data. These data, together with the good agreement between the theoretical and the experimental pair distribution functions, indicate that the here established model is useful to describe density, elasticity and short range order of Co-Fe-Ta-B metallic glass thin films. Irrespective of the investigated variation in chemical composition, (Co,Fe)-B cluster formation and Co-Fe interactions are identified by density of states analysis. Strong bonds within the structural units and between the metallic ...

The new bulk metallic glass-forming alloy was designed by Dr. Charles C. Hays in the materials science laboratories of Dr. Bill Johnson of Caltech. It is a complex mixture of zirconium, niobium, copper, nickel, and aluminum. The atoms of metallic glasses solidify in a random fashion, unlike metals, which have an ordered crystalline structure. This disordered atomic state makes metallic glasses useful in a wide range of applications, from aircraft components to high-tech golf clubs. The Genesis metallic glass was prepared in a collaborative effort by Hays and George Wolter of the Howmet Corporation, Greenwich, Conn., using the same process the company uses for the high-tech Vitreloy- based golf clubs ...

Bioglass 45S5, commonly referred to by its commercial name Bioglass, is a glass specifically composed of 45 wt% SiO2, 24.5 wt% CaO, 24.5 wt% Na2O, and 6.0 wt% P2O5. Glasses are non-crystalline amorphous solids that are commonly composed of silica-based materials with other minor additives. Compared to soda-lime glass (commonly used, as in windows or bottles), Bioglass 45S5 contains less silica and higher amounts of calcium and phosphorus. The 45S5 name signifies glass with 45 weight % of SiO2 and 5:1 molar ratio of calcium to phosphorus. This high ratio of calcium to phosphorus promotes formation of apatite crystals; calcium and silica ions can act as crystallization nuclei. Lower Ca:P ratios do not bond to bone. Bioglass 45S5s specific composition is optimal in biomedical applications because of its similar composition to that of hydroxyapatite, the mineral component of bone. This similarity provides Bioglass ability to be integrated with living bone. This composition of bioactive glass is ...
The conversion of bioactive glass to a calcium phosphate material, typically hydroxyapatite (HA), by solution-precipitation reactions in aqueous phosphate solution, has been commonly reported. This paper describes the structural and compositional characteristics of the calcium phosphate material formed during the early-stage conversion (o5 h) of a borosilicate glass (designated H12) in aqueous phosphate solution. Disks of H12 glass were reacted with 0.25M K2HPO4 solution with a starting pH57.0 at 371C. The structure and composition of the product layer were characterized using thin film X-ray diffraction, scanning electron microscopy, and Fourier transform infrared reflectance spectroscopy. For reaction times o5 h, the results indicated the formation of brushite (CaHPO4 .2H2O) with coarse, plate-like crystals. In comparison, the formation of HA with small needle-like crystals was found at later times. This early-stage formation of brushite has not been reported in previous studies of converting

In June 2011, the National Toxicology Program (NTP) removed from its Report on Carcinogens all biosoluble glass wool used in home and building insulation and for non-insulation products.[24] However, NTP considers fibrous glass dust to be reasonably anticipated [as] a human carcinogen (Certain Glass Wool Fibers (Inhalable)).[25] Similarly, Californias Office of Environmental Health Hazard Assessment (OEHHA) published a November, 2011 modification to its Proposition 65 listing to include only Glass wool fibers (inhalable and biopersistent).[26] The actions of U.S. NTP and Californias OEHHA mean that a cancer warning label for biosoluble fiber glass home and building insulation is no longer required under federal or California law. All fiberglass wools commonly used for thermal and acoustical insulation were reclassified by the International Agency for Research on Cancer (IARC) in October 2001 as Not Classifiable as to carcinogenicity to humans (Group 3).[27].

Pulsed electrical discharge (PED) is a method that has been employed to fabricate metallic glass (MG) layers on Al-Cu-Mg-(Zn) alloys. Abnormal Al and Cu element segregation has been found on the alloys vitrified surfaces after PED treatment. Surface element evaporation was found and proven to be the main reason for such significant segregation. Benefits to the evaporation of the non-corrosion resisting elements in the MG layers, the corrosion resistance, and the surface hardness of Al-Cu-Mg-Zn alloys have been greatly improved. The average corrosion rates of Al-Cu-Mg-Zn alloys with MG layers were reduced to about 2% of that without MG layers. Additionally, the surface hardness of Al-Cu-Mg-Zn alloys with MG layers was increased to 537.173 (±7) HV0.1. PED treatment is a promising way to synthesize MG layers with controllable element proportions and distributions for wear- and corrosion-resistant coatings on traditional Al-Cu-Mg-Zn alloys.

We have studied the relationship between the initial glass composition and the structural changes associated with laser-induced refractive index modification in a series of Er-Yb doped and undoped zinc phosphate glasses. White light microscopy and waveguide experiments are used together with Raman and fluorescence spectroscopy to characterize the structural changes. The correlation between Raman peak shifts and fluorescence from phosphorus-oxygen hole center (POHC) defects indicates that fs-laser writing results in a depolymerization of the phosphate glass network. The results also show that the exact glass composition should be taken into account when fabricating waveguide devices in phosphate glasses, in order to both expand the fs-laser processing conditions and maximize favorable morphological changes for 3-D photonic devices. © 2011 Optical Society of America.

Hollow glass microspheres made from a low heat conductivity glass composition containing a high vacuum and a thin metal coating deposited on the inner wall surface of the microspheres are described. The hollow glass microspheres are used to make superior insulation materials in the construction of highly efficient solar energy collectors. The hollow glass microspheres are made by forming a liquid film of molten glass across a coaxial blowing nozzle, applying a metal vapor blowing gas at a positive pressure on the inner surface of the glass film to blow the film and form an elongated cylinder shaped liquid film of molten glass. A transverse jet is used to direct an inert entraining fluid over and around the blowing nozzle at an angle to the axis of the blowing nozzle. The entraining fluid as it passes over and around the blowing nozzle fluid dynamically induces a pulsating or fluctuating pressure field at the opposite or lee side of the blowing nozzle in the wake or shadow of the coaxial blowing nozzle.

There are two types of viscosity that we usually deal with; kinematic and dynamic viscosity. Kinematic viscosity is a measure of a fluids internal resistance to flow under the force of gravity, and is usually given in the units of centistokes, cSt. Dynamic viscosity is a measure of a fluids resistance to flow when there is an external force, and has the units of centipoise, cP. For pump analysis dynamic viscosity is generally more useful, but kinematic viscosity does have application - especially for Newtonian liquids, and if you find yourself needing to measure the kinematic viscosity then a glass capillary is the simplest way.. The glass capillary is usually several hundred millimeters tall, and is made with precise length and inside diameter dimensions. It will have show two marks on the capillary, and the kinematic viscosity is determined by simply measuring the time it takes for a known quantity of the liquid to flow through the capillary between the two marks, and multiplying it by a ...

PY - 2013/4. Y1 - 2013/4. N2 - The kinetics associated with the glass transition is investigated using differential scanning calorimetry (DSC) for germanium selenide glasses with Ge content ranging from 0 to 30 at.% and average coordination numbers ranging from 2.0 to 2.6. As Ge content increases, the glass transition region broadens and the step change in heat capacity at Tg decreases. As a result of physical aging, enthalpy overshoots are observed in DSC heating scans and the corresponding change in enthalpy can be calculated as a function of aging time. The change in enthalpy linearly increases with the logarithm of aging time and then levels off at an equilibrium value that increases with decreasing aging temperature. The time required to reach equilibrium increases with decreasing aging ...
Research on solution-derived ferroelectric thin-films and melt-derived ferroelectric glass-ceramics was conducted in parallel with considerable overlap in the compositions studied and the evaluations of the crystallization behavior, microstructural development, and resulting properties. Lead germane based ferroelectric thin films were developed with a room temperature pyroelectric coefficient over 90% of the single crystal value, and a pyroelectric figure of merit exceeding the highest reported value for oriented lead titanate films. New glass-ceramic compositions were developed based on the crystallization of ferroelectric phases of lead zirconate titanate and lead zinc niobate in lead borosilicate glass matrices. The compositions in glass powder form densified at temperatures less than 900 deg C by a combination of viscous and liquid phase sintering mechanisms. Crystallization of an interconnected microstructure of the ferroelectric phases was critical to produce ferroelectric properties, and allow
Geochemical evidence indicates PAHs associated with pyrogenic sources behave differently than PAHs from petrogenic sources. There is also some evidence and supposition that PAHs from pyrogenic and petrogenic sources demonstrate differing bioavailability. In this study, we evaluated the bioavailability of PAHs from pyrogenic and petrogenic sources using a simple exposure system and glass fish. Glass fish are modified semi-permeable membrane devices (SPMDs) constructed of small borosilicate glass vials filled with either triolien or iso-octane (lipid phase) and capped with a polyethylene membrane. Accumulation of PAHs in the lipid phase of the glass fish was used to indicate PAH bioavailability. Petrogenic PAH materials included creosote, fuel oil and crude oil while pyrogenic PAH materials consisted of diesel soot, tire rubber and coal dust. Blank and reagent treatments were also conducted as negative and positive controls, respectively. Pyrogenic and petrogenic materials were added to the ...

20Li(2)O-80TeMO(2) glasses were heat annealed at different temperatures between T-g and T-x and studied by using XRD, FTIR spectroscopy and DSC techniques to understand the crystallization kinetics in this glass matrix. The infrared band structure of this glass is similar to what was observed in glassy TeO2. XRD results reveal the presence of three distinct crystalline gamma-TeO2, alpha-TeO2 and Li2Te2O5 phases during the crystallization process. This is a first report of gamma-TeO2 phase crystallization in this glass matrix. DSC results confinn the crystallization of three distinct structures in the glass. In summary, our results suggest a crystallization hierarchy on this glass matrix since the gamma-TeO2 and alpha-TeO2 phases crystallization occurs before the Li2Te2O5 phase crystallization.

Wine glass, possibly used as a culture glass by Joseph Lister Glassware of the type that fills laboratories today was rare in Joseph Listers time (1827-1912). Lister would have used glassware from his kitchen for his microbiological experiments on blood and urine. In the 1870s, he found that samples of blood and urine stored in uncovered glasses decomposed. He concluded that something in the air caused decomposition, rather than the air alone. The wine glass is shown here with similar examples. ...
Now my question is if we use a highly monochromatic light of frequency more than the phonon spectrum of glass then, light would transmit through glass by the process of to absorbtion of photons by the lattice and again re-emission and we must get intensity at the end of glass slab equal to the intensity incident.But in reality this does not happen , some energy is absorbed by the slab and we dont get intensity of wave emerging out of slab equal to incident intensity.Why it is so???? Why some photons do get permanently absorbed by the glass plate,even if all of them had energy beyond the phonon spectrum of glass???? Ideally, all the identical photons having energy beyond the phonon spectrum of glass should have been emitted as told by ZapperZ that if the photon has an energy beyond the phonon spectrum, then while it can still cause a disturbance of the lattice ions, the solid cannot sustain this vibration, because the phonon mode isnt available and none of them(photons) should have been ...
