Acceptability and Appeal of a Web-Based Smoking Prevention Intervention for Adolescents.

English: Cigarette smoking has been identified as the most important source of preventable morbidity and premature mortality worldwide (American Lung Association, 2002). Statistics show that youth who do smoke report having their first cigarette while in middle school, thus this is a critical opportunity for prevention (Eissenburg & Balster, 2000). This project helps expand current knowledge of adolescent smoking prevention programs by demonstrating an understanding of adolescents’ preference for and acceptability of the Internet in the delivery of a smoking prevention intervention. A qualitative usability study was conducted among middle school students using focus groups. Results found that the Internet is a good choice for delivery of a prevention program due to its accessibility, including the availability in most schools. Elements of interactivity and expert-trusted guidance were identified as appealing. In addition, the use of pictures and graphics in conjunction with text, can be useful in reaching students with varied learning styles. By using this non-traditional approach, health education and promotion can work in parallel with the schools, parents, and community in the delivery of effective smoking prevention programs delivered via the Internet. Spanish: El fumar cigarillos ha sido identificado como la fuente mas importante de enfermedad prevenible y mortalidad premature en todo el mundo (American Lung Association, 2002). Las estadIsticas muestran que los jovenes que fuman reportan que fumaron su primer cigarillo en la escuela secundaria, lo que constituye una oportunidad muy valiosa para la prevencion (Eissenburg & Balster, 2000). Este proyecto ayuda a expandir el conocimiento actual de los programas de prevencion de fumar para adolescentes al demostrar un entendimiento de las preferencias de los adolecentes hacia el Internet como medio de distribucion de intervenciones para la prevencion de fumar. Un estudio cualitativo del uso de estas intervenciones fue desarrollado entre estudiantes de secundaria usando grupos focales. Los resultados revelaron que el Internet es una opcion buena para la distribucon de programas de prevencion debido a su accesibilidad, incluyendo la disponibilidad en muchos de los colegios. Los elementos de interactividad y la guia de exoertos confiables fueron identificados como atractivos para este grupo. Ademas, el uso de fotos y graficos en conjunto con el texto puede ser muy util en llegar a los estudiantes con una variedad de estilos de aprendizaje. Al usar este metodo no tradicional, la educacion en salud y promocion de la salud pueden trabajar paralelamente con los colegios, padres, y comunidad en el desarrollo de programas efectivos de prevencion del uso del cigarillo distribuidos a traves del Internet.

A fiber optic sensors system for load monitoring on aircraft landing gears

We report on the use of Fiber Bragg Grating (FBG) sensors integrated onto an aircraft landing gear for remote and realtime load monitoring. Several FBGs strain sensors, both in a linear and tri-axial configuration, have been integrated on different locations of true landing gears (both Main and Nose gears) based on their load condition derived from FEM numerical analysis and exposed to numerous qualification lab tests where the load applied to the gears was varied in the range 0-20kN. To this aim, the gears were mounted on a 25kN hydraulic press, that changed the shock absorber route from 0 mm up to 200 mm (corresponding to the maximum take-off weight,~4600 kg). Obtained results are in good agreement with those provided by reference electrical strain gauges located very close to their optical counterparts, and demonstrate the great potentialities of FBG sensors technology to be employed for remote and real time load measurements on aircraft landing gears.

Usefulness of microspheres composed of gelatin with various cross-linking density

The release rate of insulin, as a model peptide, from gelatin microspheres (GM) prepared with gelatin having various cross-linking densities in vitro was examined. The release of insulin from GM showed the burst effect, followed by a slow release phase regardless of the cross-linking density of gelatin. The total amount of insulin released in 2 weeks decreased with increasing cross-linking density of gelatin. The release rate of insulin within 6h was well correlated with the cross-linking density of gelatin. The remaining amounts of both insulin and GM after injection of insulin incorporated in GM to mice femoral muscle tissue were also examined in vivo. Both insulin and GM rapidly disappeared from the injection site within 1 day, and thereafter slowly disappeared over 14 days. The time courses of the remaining amounts were fairly similar to each other. Furthermore, the remaining amount of insulin 1 day after administration was well correlated with the cross-linking density of gelatin. These data suggest that insulin was released from GM with the degradation of GM in mice muscular tissue and that the release rate of insulin can be controlled by modifying the cross-linking density of gelatin. In conclusion, the control of the release rate of insulin from GM can be achieved under both in vitro and in vivo conditions by gelatin through the alteration of cross-linking conditions.
Accurate Parental Perception as a Milestone in Managing Childhood Obesity

Objective: There were three objectives of this study: to determine the accuracy of parental perception of their child’s weight status; to compare parent and child perception of the child’s weight status; and, to ascertain if comments from the child’s health professional about the child’s weight status was related to the accuracy of the parent’s perception. Methods: Using NHANES 2011-2012 data, chi square analysis (p<0.05) and weighted Kappa were used to examine parental perception and accuracy (n=2,775), child perception and accuracy (n=1,387), and comments to parents from a health professional (n=2,959). Secondary analysis examined socio-demographic and lifestyle factors that may be related to accuracy of parental perception (n=2,774). Subgroup analyses were conducted for overweight/obese children (n=882). Results: Overall, 24.7% of parents and 29.6% of children underestimated the child’s weight status. For overweight/obese children, 60.1% of parents and 60.4% of children underestimated the child’s weight status. Almost 90% of parents did not recall a conversation with a health care provider about their child’s weight status. The study hypothesis was confirmed that there was significant parental underestimation of child’s weight status regardless of child age, gender, race, or household income. Conclusions: Parents and children need accurate perception of weight status in order to initiate weight management strategies. Improved communication between health professionals and parents of overweight/obese children could assist parents attain accurate perception of their child’s weight.

Petrogenesis of the Neoproterozoic strongly peraluminons granitoids from Northern Guangxi:constraints from zircon geochronology and Hf isotopes.

The western end of the Proterozoic Jiangnan orogen is located at Northern Guangxi,South China.Neoproterozoic strongly peraluminous granitoids are dominant(＞90%)in the area,with ca.8%being the mafic-ultramafic rocks.The granitoids in Northern Guangxi can be geochemically divided into two groups:granodiorites and granites.Their generations were previously considered to be related to a mantle plume(or superplume)event that led to the breakup of the Rodinia supercontinent.In this work,we present new laser ablation (LA)-ICP-MS U-Pb zircon dating and LA-MC-ICP-MS zircon Hf isotopic results for the granitoids from Northern Guangxi.The ages for the Zhaigun,Bendong,Dongma,Sanfang and Tianpeng granitic plutons are 835.8±2.5Ma,822.7±3.8Ma, 824±13Ma,804.3±5.2Ma and 794.2±8.1Ma,respectively.These dating results suggest that the two types of the granitoids in the area were formed in two episodes.The granodiorites formed at ca.835±820Ma,whereas the granites emplaced at ca.810～800Ma. The analyses for 8 spots of zircon cores and 2 spots from single zircon xenoliths show early Neoproterozoic ages ranging from ca.870 Ma to 950 Ma.These ages might record the subduction or collision-related magmatic events during 950～870 Ma in Northern Guangxi.Hf isotopes of zircons were also analyzed by La-MC-ICP-MS.The(~(176)Hf/~(177)Hf)_i ratios for the zircons from the Bendong,Sanfang and Tianpeng plutons are 0.282176±0.000021,0.282149±0.000021 and 0.282175±0.000030,respectively.Coupling zircon Hf isotopes and published whole rock Nd isotopes data suggest a basement sedimentary series source for the granitoids and the involvement of relatively more mantle-derived marie materials in the source of the granodiorites.The dating results also reveals a ca.35Ma magmatic duration,which is inconsistent with the plume models that predict widespread magmatic eruption and emplacement within period of 1- 5Ma.The Neoproterozoie granitoids from Northern Guangxi are generally plotted in the collision-related and post-collisional granites areas in the tectonic discrimination diagrams.They have been formed after the collision peak(ca.870 Ma) between the Yangtze and Cathysia blocks,belonging to the post-collisional granites.The upwelling of deep mantle due to the detachment of subdueted slab and the delamination of the lithosphere might cause the partial melting of the basement rocks to generate the strongly peraluminous granitoids.
Geophysical monitoring of the CO2 plume at Sleipner, North Sea : an outline review

CO2 produced at the Sleipner gas field is being injected into the Utsira Sand, a major saline aquifer some 1000m beneath the North Sea. The injection plume is being monitored by geophysical methods. 3D seismic data were acquired in 1994, prior to injection, and again in 1999, 2001 and 2002; seabed gravimetric data were acquired in 2002. The CO2 plume is imaged on the seismic data as a number of bright sub-horizontal reflections, growing with time, underlain by a prominent velocity pushdown. Quantitative modelling is based on plume reflectivity largely comprising tuned responses from thin layers of CO2 trapped beneath thin intra-reservoir mudstones, layer thicknesses being mapped according to an amplitude-thickness tuning relationship. Between the layers, a lesser component of much lower saturation dispersed CO2 is required to match the observed velocity pushdown. However, reservoir temperatures are subject to significant uncertainty, and inverse models of CO2 distribution, based on lower and higher temperature scenarios, can both produce the observed plume reflectivity and the velocity pushdown. Higher temperature models however require that the dispersed component of CO2 has a somewhat patchy, rather than uniform saturation. Analysis of the datasets suggests that accumulations of CO2 as small as 500 tonnes may be detectable under favourable conditions, providing a basis for setting leakage criteria. To date, there is in fact no evidence of migration from the primary storage reservoir.

Sintered Iron-Rich Glass-Ceramics and Foams Obtained in Air and Argon

The subsequent synthesis of sintered self-glazed glass-ceramics and/or glass-ceramic foams using metallurgical slag is the topic under discussion. The observed intensive sample expansion can be considered as an autocatalytic process related to the oxygen release due to thermal reduction of Fe 2 O 3 and MnO 2 present in the slag. The sintering of the samples is studied by optical dilatometry and the foaming process by hot-stage microscopy, while the structure of the final materials is revealed by 3-D computed tomography and SEM. The phase composition of the glass-ceramic foams is analyzed by XRD. The species are characterized by moderate crystallinity, 80–85 vol.% porosity and fire resistance above 1000°C. The innovative point of this study is the synthesis in argon of sintered glass-ceramic materials where reduction is inhibited, together with a double-stage foam formation in air and argon, leading to lower working temperatures and better material characteristics.
Effect of Concrete Waste on Compressive Strength and Microstructure Development of Ceramic Geopolymer Pastes

ABSTRACT Ceramic industry generates a large amount of wastes, which pollutes and damages the environment. This paper presents the effects of concrete waste incorporating dolomite aggregate on ceramic-based geopolymer pastes in terms of microstructure and compressive strength. Recently, attention has been drawn to the use of geopolymer technology in the production of building units. Geopolymers were prepared from alkali activation of ceramic waste by 6%, 8%, 10% and 12% NaOH. To enhance the mechanical properties, alkali-activated ceramic geopolymer with 10% and 12% NaOH was partially substituted with concrete waste containing dolomite coarse aggregate at proportions of 5%, 10%, 15%, 20% and 30% by weight. Likewise, other geopolymer mixtures were manufactured by replacing ceramics with 5%, 10%, 15%, 20% and 30% calcined concrete waste at 850oC. Water/binder ratio as well as compressive strength of all mixtures was determined at 1, 7, 14 and 28 days. Phase composition and microstructure of geopolymer were identified using Fourier transform infrared spectroscopy and scanning electron microscopy techniques. Incorporation of 10% concrete waste and 20% calcined concrete waste enhanced the compressive strength and the microstructure of ceramic geopolymer pastes, while embedding extra amounts led to adverse effects. GRAPHICAL ABSTRACT
The Effect of Two Bulk-Fill Resin Composites on Fracture Resistance of Endodontically Treated Teeth

Objectives: The aim of this study was to compare the effect of two commercially available bulk-fill restorative materials on the fracture resistance of endodontically treated human molar teeth. Materials and methods: A total of 44 mandibular third molar were divided into four groups: Group 1; 4 mm thick bulk-fill fluid composite (SDR ™, Dentsply, Konstanz, Germany) was applied to the cavities. The restoration of the proximal walls and the occlusal region was completed with posterior composite (Valux Plus, 3M ESPE, St. Paul, MN, USA ). Group 2; 4 mm thick fiber-resin reinforced bulk-fill composite (EverX Posterior; GC Corp., Japan) was placed in the cavities and the procedure in Group 1 was repeated. Group 3 (negative control group); no restoration was applied to the cavities. Group 4 (positive control group); comprised intact molar teeth without any treatment. The root canals were shaped using rotary instruments, irrigated with NaOCl, and obturated. All samples were incubated in distilled water at 37˚C for 1 week and then fracture strength test was performed. The values were recorded in Newton and the data were evaluated using Kruskal Wallis and Mann-Whitney U test. Results: No statistically significant difference ( p >0.05 ) was observed between group 1, 2, and the positive control group. However, the bulk-fill fluid composite material showed higher fracture resistance than the fiber-resin reinforced composite material ( p<0.05) . The highest fracture resistance was observed in the positive control group. The fracture resistance of the negative control group was statistically lower than the other groups ( p<0.05) . Conclusions: Both of the bulk-fill restorative materials in endodontically treated teeth showed similar fracture resistance to intact teeth. In addition, the clinical use of the bulk-fill fluid composites may be recommended because of their high fracture resistance and ease of application.

Association between soil .. transmitted helminthiasis and hemoglobin concentration in primary school children

Objectives To determine the association between intestinal hel- minthiasis and hemoglobin (Hb) concentration and to observe the effect of single dose albendazole treatment on Hb concentration. Methods An experimental study was carried out from March to July 2002 on primary school children at Suka Village, Tiga Panah Subdistrict, Karo Regency, North Sumatera Province. From 366 children who suffered from helminthiasis, 113 were selected as subjects by simple random sampling. Subjects were treated with a single oral dose of 400 mg albendazole. Hb concentration was examined using the cyanide method twice i.e., prior to and three months after treatment with albendazole. Results It was found that among 113 subjects, the prevalences of Ascaris lumbricoides, Trichuris trichiura, and mixed infestation were 18.3%, 40.4%, and 41.3%, respectively, while the prevalence of anemia was 33.0%. There was no significant difference in age, gender, nutritional status, and mean Hb concentration between children suffering from the different types of worm infestation (P>0.05). For each type of infestation, there were significant differ- ences in mean Hb concentration and anemia prevalence before and after treatment (P<0.05). Conclusions There was no difference between the Hb concen- trations of children suffering from Ascaris lumbricoides, Trichuris trichiura, and mixed-type worm infestations. Single dose 400 mg albendazole was beneficial in increasing Hb concentration and reducing the occurrence of anemia
Behavior of precast reinforced concrete columns subjected to monotonic short-term loading

This paper presents a case study on the behavior of precast reinforced columns with non-conventional cross-section. An experimental program was developed to verify the serviceability and ultimate limit states of these columns, loaded with eccentric compression forces. In addition, results obtained through a theoretical model based on the Brazilian standard ABNT NBR 6118:2014 and a Finite Element numerical model using ANSYS software were presented. Analysis of the results showed that the proposed models satisfactorily predicted column behavior. However, the ultimate strength of the column could not be determined due to limitations in the formulation of the theoretical model. The numerical model presented good agreement with the experimental results, both in serviceability and in ultimate limit state.

Theories of soil creep have been reviewed and rheological processes occurring in them under natural conditions have been discussed. Laboratory set ups and techniques to determine instantaneous and creep strains in clayey soils have been described. The effect of residual pore pressure and lateral pressure on volumetric and shear strains has been studied and the relation between volumetric and shear strains has been described with particular reference to long-term shear strength of clayey soils, etc. The book should be useful to students of civil engineering and geological sciences.
Phase transition and energy transfer of lead-free Cs2SnCl6 perovskite nanocrystals by controlling the precursors and doping manganese ions

Perovskite quantum dots (QDs), such as all-inorganic CsPbX3 (X = Cl, Br, and I), are novel fluorescent semiconductor nanocrystals (NCs) that have attracted tremendous attention due to their excellent optical properties and great applications (e.g. display backlights, light-emitting diodes, and photodetectors). The instability and toxicity of lead-based perovskite QDs, however, are intrinsic defects that obstruct their application and commercialization. Poison is released from the lead of the unstable CsPbX3 NCs, which are generally ascribed to the labile surface, ionic character, and metastable structure. In this work, lead-free Cs2SnCl6 perovskite NCs are successfully synthesized via hot injection. Particularly, by controlling the different precursor ratios, phase transition (CsCl to Cs2SnCl6) was clearly observed from X-ray diffraction (XRD) measurements. The Cs2SnCl6 NCs exhibited a highly efficient deep-blue emission at 425 nm, with a 55 nm Stokes shift and an 84 nm full width at half maximum (FWHM). After doping Mn ions, the preferred formation of CsSnCl3:Mn2+ with double-wavelength emission was demonstrated based on the XRD and photoluminescence spectra. The study showed that doping synthesis should be widely used in lead-free perovskite NCs as an important strategy for next-generation solid-state lighting.
