Abstract The lipid/resin components of Laretia compacta were characterized by GC-MS and CSIA. The lipid components consist of n-alkanes, n-alkanoic acids and n-alkanols all with low carbon number maxima and high CPI values. The resin components are comprised of major amounts of tetracyclic diterpenoids with a minor content of mono-and sesquiterpenoids. The kaurene skeleton predominates with some phyllocladenes. Phytosterols are trace components. The δ13C data of the individual alkanes in the hydrocarbon fraction place this species in the C4 plant group.

During the drilling operations of Danish American Prospecting Co. in Denmark 1946-1959 several mineral water occurences were encountered in the subsurface.Samples taken from Zechstein deposits show a composition ranging from concentrated almost pure MgCl2- or CaCl2-solutions to solutions more dominated by NaCl. Usually they seemn to be migrating solutions which have secondarily reacted with the salt deposits they have penetrated.Samples from Jurassic and Danian deposits are more diluted NaCl-solutions with a minor content of CaCl2 and MgCl2.The diluted mineral waters of Denmark are regarded as mixtures of concentrated salt solutions and fresh water.Uniform composition of diluted mineral waters does not necessitate a uniform composition of the original concentraled salt solutions. It may also be brought about by ion exchange reactions between clays and salt solutions of different composition as e.g. the above-mentioned solutions encountered in the Zechstein deposits.

Seek for new Rare Earth Elements (REE) sources encourage looking for easily available sources located in Europe. REE in evolved magmatic systems are predominantly associated with alkali environments. Therefore, it was decided to identify the content of REE in alkali igneous rocks of the Winna Góra basalt quarry located in Lower Silesia, Poland. In this study, a commercially available basalt aggregate from Winna Góra deposit located in the south-western part of Poland near Jawornik was examined for REE content. Mineral content and chemical composition were examined with a light microscope, XRD and XRF, whereas trace element content was measured with the ICP-MS technique. A new method of sample preparation for the purpose of REE identification in basalt aggregate based on pressure microwave mineralisation was developed. Mineral composition and TAS diagram classify aggregate as tephrite. The mineral composition of samples reflects typical mafic and ultramafic rocks. Quantitative mineralogical analysis by the Rietveld method showed that the main minerals are anorthite (46.7%) and augite (37.4%) with a minor content of forsterite (7.5%), nepheline (7.4%) and apatite below 1%. The total content of REE does not exceed 132 ppm. Chondrite normalised curves show the highest concentration of La and Pr. In the case of HREE, the majority of elements (Eu, Tb, Dy, Ho, Er, Yb) concentrations were below 1 ppm, a Tm and Lu were not detected. The low enrichment in HREE was also reflected in La/Gd ratios. Obtained results are comparable to the REE contents in the western part of the Cenozoic European Volcanic Province.

Ti3SiC2/20vol%SiC composite was synthesized by spark plasma sintering (SPS) under a pressure of 50MPa at 1350°C using Ti, Si and C as starting powders. The phase constituents and microstructures of the composite were investigated. X-ray diffraction (XRD) results demonstrated that Ti reacted with C to form TiC firstly, then TiSi2 formed from Ti and Si. The formation of Ti3SiC2 might come from two reactions. One was that TiSi2, Ti and TiC reacted directly to form monolithic Ti3SiC2. The other one was that TiSi2, Ti and C reacted to form Ti3SiC2 and SiC. The EPMA results showed that the main phases were Ti3SiC2 and SiC with a minor content of TiC as impurity. TiC particles less than 1μm in diameter distributed in SiC phase.

Abstract The AMA Guides to the Evaluation of Permanent Impairment, Fourth Edition, uses the Injury Model to rate impairment in people who have experienced back injuries. Injured individuals who have not required surgery can be rated using differentiators. Challenges arise when assessing patients whose injuries have been treated surgically before the patient is rated for impairment. This article discusses five of the most common situations: 1) What is the impairment rating for an individual who has had an injury resulting in sciatica and who has been treated surgically, either with chemonucleolysis or with discectomy? 2) What is the impairment rating for an individual who has a back strain and is operated on without reasonable indications? 3) What is the impairment rating of an individual with sciatica and a foot drop (major anterior tibialis weakness) from L5 root damage? 4) What is the rating for an individual who is injured, has true radiculopathy, undergoes a discectomy, and is rated as Category III but later has another injury and, ultimately, a second disc operation? 5) What is the impairment rating for an older individual who was asymptomatic until a minor strain-type injury but subsequently has neurogenic claudication with severe surgical spinal stenosis on MRI/myelography?

Abstract Pelvic fractures are relatively uncommon, and in workers’ compensation most pelvic fractures are the result of an acute, high-impact event such as a fall from a roof or an automobile collision. A person with osteoporosis may sustain a pelvic fracture from a lower-impact injury such as a minor fall. Further, major parts of the bladder, bowel, reproductive organs, nerves, and blood vessels pass through the pelvic ring, and traumatic pelvic fractures that result from a high-impact event often coincide with damaged organs, significant bleeding, and sensory and motor dysfunction. Following are the steps in the rating process: 1) assign the diagnosis and impairment class for the pelvis; 2) assign the functional history, physical examination, and clinical studies grade modifiers; and 3) apply the net adjustment formula. Because pelvic fractures are so uncommon, raters may be less familiar with the rating process for these types of injuries. The diagnosis-based methodology for rating pelvic fractures is consistent with the process used to rate other musculoskeletal impairments. Evaluators must base the rating on reliable data when the patient is at maximum medical impairment and must assess possible impairment from concomitant injuries.

In serial memory for spatial information, some studies showed that recall performance suffers when the distance between successive locations increases relatively to the size of the display in which they are presented (the path length effect; e.g., Parmentier et al., 2005) but not when distance is increased by enlarging the size of the display (e.g., Smyth & Scholey, 1994). In the present study, we examined the effect of varying the absolute and relative distance between to-be-remembered items on memory for spatial information. We manipulated path length using small (15″) and large (64″) screens within the same design. In two experiments, we showed that distance was disruptive mainly when it is varied relatively to a fixed reference frame, though increasing the size of the display also had a small deleterious effect on recall. The insertion of a retention interval did not influence these effects, suggesting that rehearsal plays a minor role in mediating the effects of distance on serial spatial memory. We discuss the potential role of perceptual organization in light of the pattern of results.
