Valuation of Risk Management in Construction Projects Through the Use of Feedback Mechanisms

Field: Engineering (Physical Sciences)

Experience feedback data can have different types depending on the civil engineering sector for example experimental measurements, expert information, visual observation, these formats can provide several different practices for capitalizing on experience feedback, processing and finally valuation of the information capitalized for the diagnosis. The current article addresses the application of experience feedback to construction sites. As we shall argue, if the concept of experience feedback is applicable it would appear that the devices implemented in the construction sites are not taken into consideration and that, consequently, this sector faces significant risks. This present study enables us to propose an approach to improve experience feedback by taking into account the existence of different practices in a construction site. We shall argue that the implementation of a safety case makes it possible to promote the creation of a communication link between community of practice centered around experience feedback (REX) which systematically promotes the improvement of the practice of this device.
Race, Socioeconomic Status, and the Subjective Well-Being of Older Americans

Field: Social Sciences (Social Sciences)

Causal examination of factors influencing life satisfaction among older Americans can provide knowledge important to social policy development. Using rotated factor analysis, this study isolates two dimensions of life satisfaction, labeled happiness and morale, using data from the 1981 Harris survey on aging. Race, SES characteristics, and the two intervening variables of self-assessed health status and problems experienced are tested through path analysis on the two attributes of life satisfaction. Most of the effects of race and SES are mediated by self-assessed health status and problems experienced, and these two intervening variables are the strongest direct predictors of happiness and morale. Of particular significance are results which demonstrate that racial background has a strong influence on problems experienced, and that education is more influential than income on the life satisfaction factors tested in this study.
On the structure, synthesis, and characterization of ultrafast blue-emitting CsPbBr3 nanoplatelets

Field: Materials Science (Physical Sciences)

Recent developments in medical imaging techniques, in particular, those in time-of-flight positron emission tomography put new challenges on scintillating material performance that cannot be fulfilled by conventional scintillators. Bright and ultrafast nanoparticles represent promising candidates to build up an advanced detection system needed. We synthesize colloidal CsPbBr3 nanoplatelets emitting blue light with fast sub-nanosecond decay. We also prepare a nanocomposite material by embedding the nanoplatelets in the polystyrene matrix. We show that blue emission is preserved provided the composite is not exposed to UV/vis light and/or elevated temperatures. Motivated by conflicting information from the literature about the room temperature structure of colloidal CsPbX3 (X = Cl, Br, I) particles, that results being orthorhombic, rather than cubic, we perform ab initio electronic structure calculations of bulk crystals with an orthorhombic structure. We calculate optical properties, as well as exciton diameters and binding energies and compare them to those previously obtained for cubic CsPbX3 crystals.
Smart Contract Vulnerability Detection Based on Symbolic Execution Technology

Field: Computer Science (Physical Sciences)

Abstract With the rapid development of the blockchain, smart contract technology has been widely applied. The number of smart contracts has grown at a high rate and nearly at an average of thousands per day. However, the correctness and security of the smart contract itself are facing huge problems. The well-known DAO vulnerability, and Parity multi-signature wallet’ vulnerabilities have leaded to a hundreds of millions dollars loss, and they are both caused by the security problems of smart contracts. Once the smart contract vulnerability is exploited, it is very likely to bring the loss of cryptocurrencies, the disorder of the financial order and other catastrophic consequences. Therefore the security of smart contracts is imminent. This project has designed and implemented a vulnerability detection system of Ethereum smart contract. The system uses the assembly instruction sequences of the smart contract to generate the control flow graph, then performs symbolic execution and vulnerability constraint solving over the control flow. The system can detect some common types of vulnerabilities, such as the integer overflow and underflow vulnerability, reentry vulnerability and unchecked call return value vulnerability. It has a high accuracy of detection result, and gives support for export vulnerability report.
Internal rock damage during landsliding: Kinematic effects

Field: Earth and Planetary Sciences (Physical Sciences)

Actual deformation mechanisms during sliding are a consequence of several interacting aspects: the geometry of the basal sliding surface, the degree of heterogeneity of the moving mass, the presence of internal weak or hard zones and the stress-strain behaviour of the involved materials. Except in simple cases (pure rotational or planar motions) the development of an admissible mechanism leads to internal shearing. As a result, extensive damage may result, especially in brittle materials. The paper examines the stability conditions and the post-failure behaviour of a compound landslide whose geometry is inspired by one of the representative cross sections of Vajont landslide. The effect of the rock brittleness and stiffness will be presented. A Mohr-Coulomb elasto-plastic strain softening constitutive model defines the rock behaviour. Strength parameters are made dependent of the accumulated deviatoric plastic deformation. The cases discussed were solved by the Material Point model which is well adapted to deal with large deformations and displacements within a general dynamic formulation.
Regulating Smart Personal Devices in Restricted Spaces

Field: Computer Science (Physical Sciences)

Smart personal devices equipped with a wide range of sensors and peripherals can potentially be misused in various environments. They can be used to exfiltrate sensitive information from enterprises and federal offices or be used to smuggle unauthorized information into classrooms and examination halls. One way to prevent these situations is to regulate how smart devices are used in such restricted spaces. In this paper, we present an approach that robustly achieves this goal for ARM TrustZone-based personal devices. In our approach, restricted space hosts use remote memory operations to analyze and regulate guest devices within the restricted space. We show that the ARM TrustZone allows our approach to obtain strong security guarantees while only requiring a small trusted computing base to execute on guest devices.
SGP-TR-IS8 INTEGRATED ALTERATION MINERALOGY AND FLUID-INCLUSION STUDY

Field: Earth and Planetary Sciences (Physical Sciences)

Cuttings from geothermal wells in Dixie Valley, Nevada document the complex history of the Jurassic reservoir rocks now contained within the hanging wall of the Stillwater normal fault. Six stages of post-Oligocene alteration can be recognized on the basis of mineral paragenesis, rock associations, fluid-inclu-sion temperatures and apparent salinities. The para-genetic sequence from oldest to youngest consists of: Stage I) epidote-chlorite-calcite veins; Stage 11) illite; Stage 111) wairakite-quartz-calcite-potassium feldspar-epidote veins; Stage IV) mixed-layer illite-smectite and quartz-calcite veins; Stage V) chal-cedonic quartz-dolomite-calcite-chlorite/smectite-barite-hematite veins; and Stage VI) quartz-calcite veins. Fluid-inclusion data yield the following tem-peratures and apparent salinities in weight percent
New species of the genus Isoschizoporella (Bryozoa: Gymnolaemata: Cheilostomatida: Eminooeciidae) from the Weddell Sea

Field: Agricultural and Biological Sciences (Life Sciences)

A new species, Isoschizoporela marisweddelli sp. nov., from the bryozoan order Cheilostomatida was described within the genus endemic for Antarctic waters. Fragments of colonies of the species were found in the Weddell Sea by the German Antarctic Expedition ANT XIII/3 on the research vessel “Polarstern” in 1996. The species is distinguished from the other species of Isoschizoporella by the incrusting colony, elongate, hexagonal and convex autozooids, semicircular primary orifice with shallow sinus, strongly convex avicularian chamber, avicularium with semicircular mandible, and additional avicularium on frontal surface of autozooid. The species belongs to the infraorder Ascophora, superfamily Schizoporelloidea.
Synthesis and surface activity of poly(maleic diester) surfactants

Field: Chemistry (Physical Sciences)

A series of maleic diester monomers have been prepared by esterification of maleic anhydride with a series of n-alkanols and poly(ethylene glycol) with different molecular weights. These monomers were polymerized in acetic anhydride solution in the presence of cumene hydroperoxide as initiator. The synthesized polymers have been characterized by IR and 1H NMR spectroscopy, and their surface and thermodynamic properties as non-ionic surfactants is investigated. The surface tension as a function of concentration of the surfactant in aqueous solutions was measured at 298, 308, 318 and 328 K. The surface parameters are calculated. The data reveal that the CMC value of the polymeric surfactant is lower than that of the monomeric surfactant. It is also found that the CMC value decreases with increasing temperature and the number of ethylene oxide units in the surfactant molecule. The thermodynamic parameters of micellization and adsorption are also determined. The structural effectiveness of surface tension is discussed in terms of these parameters. © 1999 Society of Chemical Industry
Condition- and parasite-dependent expression of a male-like trait in a female bird

Field: Agricultural and Biological Sciences (Life Sciences)

In many species, females display brightly coloured and elaborate traits similar to those that males use in intra- and inter-sexual selection processes. These female characters are sometimes related to fitness, and might function as secondary sexual characteristics that have evolved through sexual selection. Here, we used descriptive data from 674 females in 10 populations and an experimental removal of Trichostrongylus tenuis parasites in four populations, to examine the effects of season, age, condition, and parasites on the size of supra-orbital combs displayed by female red grouse Lagopus lagopus scoticus . We found that comb size (i) was greater during the breeding than the non-breeding season, (ii) was greater in adult than in young females, (iii) was positively correlated with body condition, and (iv) negatively correlated with parasite abundance. Experimentally, we showed that comb size increased proportionally to the number of worms removed after parasite dosing. Our findings provide a better understanding of proximate mechanisms behind the expression of a male-like trait in females, and we discuss its possible function as a female ornament.
Nucleolar activity in the primate dorsal root ganglion cells associated with dietary protein malnutrition

Field: Neuroscience (Life Sciences)

The nucleolar changes in the dorsal root ganglion cells of the squirrel monkey, <i>Saimiri sciureus</i>, have been investigated by the use of histological and histochemical methods in the healthy neonates (born to mothers maintained on 25% protein diet during gestation) and young adults, and compared with those observed in the protein-malnourished neonates (born to mothers maintained on a 8% protein diet during gestation). Also studied were young adults maintained on a high protein diet (25% protein) as well as on a low protein diet (2% protein content) for a period of 15 weeks. Whereas in the healthy animals (neonates and young adults) only a few cells show nucleolar budding and finally their extrusion into the cytoplasm, the protein-malnourished animals show a significantly enhanced nucleolar activity in the form of increased size (3–4 times the original) and active budding either from one focal point or at several places on the body of the nucleolus. In the neurons which show chromatolytic changes, these extrusions migrate to the nuclear membrane, wherefrom they pass on to the cytoplasm through an evagination of the nuclear envelope. Such a migration appears to occur by a focal dissolution of the nuclear membrane. It appears that, under conditions of severe malnutrition and advanced chromatolytic changes in the neuronal cytoplasm, the nucleolar material provides a compensatory mechanism for the increased cytoplasmic catabolism and loss of ribonucleoprotein material in order to facilitate additional protein synthesis for cell survival.
Learning Music Blind: Understanding the Application of Technology to Support BLV Music Learning

Field: Computer Science (Physical Sciences)

Learning to play a musical instrument and engaging in musical activities have enabled blind and/or low vision people to develop self-identity, find community and pursue music as a career. However, blind and/or low vision music learners face complex obstacles to learn music. They are highly reliant on their learning environment and music teachers for accommodations and flexibility. Prior research has identified the challenges faced by blind and/or low vision musicians and recognized the importance of touch for music reading and physical guidance. However, limited research has addressed these challenges through the development of assistive technology. The development of music computer technologies with haptics and the affordances of wearable technologies provides encouraging opportunities to develop haptic wearable devices to support blind and/or low vision music learning. I identify three unexplored research questions: (1) what design considerations must be addressed in future assistive technologies for BLV music learning, (2) how can wearable technologies with vibrotactile feedback support BLV student-teacher interactions, and (3) what are the long-term benefits and limitations of the use of assistive technologies for BLV music learning? I outline my research to date and highlight my findings.
Partnership management within the virtual enterprise in a network

Field: Business, Management and Accounting (Social Sciences)

The authors propose a new management method which integrates a behavioural approach and an instrumental approach in order to answer the managerial challenges of the virtual corporation. The concept of virtual corporation, developed as an organizational theory in the United States, is gaining more ground. Communication techniques are becoming more powerful and promising. The virtual corporation has emerged as an answer to new competitive economic constraints, to offer the possibility to grasp opportunities in transitional markets. However, if the flexibility of this new organizational model constitutes the key for corporation survival, its management method is far from easy because it must combine fluidity and control, strong partnership relations and short life expectancy, differences and cohesion. They look into this real management method for the new virtual corporations.
Changes in Fertility and Morphology of Sensitized Rat Uterine Endometrium upon an Intra-uterine Injection of Antigen

Field: Medicine (Health Sciences)

Rats were immunized with BCG-vaccine or horse serum and divided into two subgroups, one containing pregnant animals, the other containing spayed animals treated with progesterone. The pregnant rats were given an intra-uterine injection of the antigen on day 3 of pregnancy and the number of foetuses was registered. The spayed rats were first given progesterone, then an intrauterine injection of the antigen, and prepared for microscopy at various intervals. The results showed that an intra-uterine injection of BCG-vaccine rendered implantation impossible and also markedly changed the structure of the endometrium. Serum, in the corresponding experiments, did not block implantation, but morphological signs of an immune reaction were present although not in the uterine epithelium. It is concluded that with the design used, an immunological reaction of the immediate-type cannot change the structure and function of the uterine epithelium sufficiently to render implantation impossible.
Methanogenesis pathways in a stratified eutrophic alpine lake (Lake Bled, Slovenia)

Field: Environmental Science (Physical Sciences)

The production pathway and carbon source of CH 4 in the surface sediment of a eutrophic alpine lake (Lake Bled, northwest Slovenia), in which the hypolimnion is anoxic for most of the year, were determined from molecular and biogeochemical studies. The average δ 13 C CH4 value of ‐69.5‰ ± 1.2‰, associated with low acetate concentrations, suggested that CH 4 should be formed, predominantly, hydrogenotrophically. The proportion of “fresh” autochthonous lipids in total extractable lipids in sediment decreased from 62% at the surface to 41% at a depth of 20 cm. The contribution of lipids of bacterial origin was more pronounced at the surface, comprising 13%. Terminal restriction fragment length polymorphism (T‐RFLP) analysis of 16S ribosomal ribonucleic acid (rRNA) sequences of bacterial and archaeal community members suggested that larger sediment‐depth‐dependent changes occurred in the latter. The majority of archaeal sequences belonged to Euryarchaeota . The methanogenic population accounted for 73% and 38% of the archaeal community at depths of 0‐2 cm and 10‐12 cm, respectively. In the upper 2 cm, hydrogenotrophs, mostly Methanomicrobiaceae , were dominant. In the deeper sediment, archaeal sequences were mostly those of unknown affiliation with Euryarchaeota , Thermoplasmatales , and related linkages, and only 21% of the hydrogenotrophic methanogenic archaea were detected. Somewhat lower percentages (< 18%) of sequences representing acetotrophic archaea ( Methanosaetaceae ) were present in the two layers. The biogeochemical processes and structure of the archaeal community support the hypothesis that hydrogenotrophic methanogenesis is the dominant pathway in the sediment of alpine Lake Bled, despite low temperature and the prevalence of “fresh” autochthonous‐derived organic matter.
Deux maladies génétiques : la drépanocytose et les thalassémies. Enquêtes en région parisienne

Field: Medicine (Health Sciences)

Neonatal screening of sickle cell discase and thalassemias in Paris : two major genetic disorders among immigrant populations from the South. Jacques ROCHETTE and Yves CHARBIT « Hemoglobinopathies » is a common term for inherited disorders of hemoglobin, the major constituant of red blood cells. Numerically, the most important are thalassemias caused by a reduced rate of synthesis of hemoglobin subunits ; and the sickle celle disease is caused by structural modifications of this protein. The hemoglobinopathies used to be very rare in Northern Europe, but since the 1950s their incidence has increased steadily because of intra-European and gobal migration. This is particularly true in France where the immigration of various ethnic groups at risk for hemoglobinopathies is growing up and amplifled by the qualitative change in these populations which include an increasing number of young women and children. It is commonly accepted that early diagnosis and prophylactic treatment of sickle cell disease can reduce mortality and morbidity. We have therefore undertaken neonatal screening for genetic hemoglobin disorders in the center and in the south suburb of Paris. Taking into account the composition of the populations the incidence of hemoglobinopathies was as expected. Beside the neonatal screening we have done, other periods could be the school medicine of young people and the antenatal clinic of pregnant women. This last procedure is the only one efficient allowing to offer genetic counselling for people at risk and the possibility of prenatal diagnosis.

The species is related to D. friedmani Grichanov, 2009 and D. madagascariensis Grichanov, 2009, differing in smaller size, brown postpedicel of antenna, male fore coxa without apical hook, fore basitarsus without apical process, wing and hypopygium structures. The following new combination is established: Dolichophorus hamatus (Parent, 1936), comb. n. (from Medetera Fischer von Waldheim, 1819). A key to five Afrotropical species of this genus is compiled.
Dephasing in Self-organized InAlGaAs Quantum Dots

Field: Physics and Astronomy (Physical Sciences)

We report the first direct measurements of dephasing in III-V semiconductor quantum dots at low temperature using degenerate four-wave mixing. At 0 K, the coherence time is limited by the population lifetime whereas pure dephasing due to exciton-phonon interactions appears only at finite temperatures. We observe a striking discrepancy between the homogenous linewidth derived from the dephasing times and the measured photoluminescene linewidth of individual quantum dots, indicating the presence of an additional inhomogenous broadening mechanism in photoluminescence measurements of single quantum dots.
Herbicide Resistant Weeds

Field: Agricultural and Biological Sciences (Life Sciences)

Herbicide performance is a complex issue that is influenced by many factors. These include spray coverage, application method, herbicide rate, environmental conditions, and weed size, to name a few. Poor or incomplete control may also be due to the ability of a weed to tolerate a particular herbicide. Herbicide tolerance is the inherent ability of a species to survive following a herbicide treatment. There was no selection to make the plant tolerant; it simply possesses a natural tolerance.
