Case study using the Los Angeles tall buildings structural design council guidelines: 40‐storey concrete core wall building

Los Angeles Tall Building Design Council (LATBDC) 2005 guidelines for analysis and design of tall buildings are utilized for the design of a 40 storey tall reinforced concrete building located in downtown Los Angeles. The case study structure is a 415 feet tall reinforced concrete residential building with 118 feet by 96 feet plan area. Lateral load carrying system of the building is bearing walls coupled with 32 to 60 inches deep spandrel beams. Gravity system consists of 8″ thick post‐tensioned concrete flat slabs resting on reinforced concrete gravity columns and bearing walls. Linear and nonlinear dynamic analysis procedures were followed using 475 and 2,475 year return period seismic events respectively. Design of core wall segments and spandrel beams connecting the segments together were controlled by both of these seismic hazard levels and analysis procedures. Nonlinear dynamic analysis of the 40 storey building showed inelastic flexural response at the spandrel beams over the building height in addition to the first few levels of the core wall segments. As intended, recorded component deformations were within the collapse prevention performance limits set by FEMA 356. The case study results highlight a significant limitation for Step 2 (Life Safety for DBE) to demonstrate achievement of ‘life safety’. Copyright © 2007 John Wiley & Sons, Ltd.
Fine Particle Dispersion and Deposition in Three Different Square Pore Flow Structures

This paper investigates numerically the motion and deposition behaviors of micro- or nano-scaled particles in fluid passing three different kinds of square pores. The three kinds of square pores represent different pore structures in porous medium. The flow fields are numerically simulated by lattice Boltzmann method (LBM). The computation procedure code was validated by comparing the results with those of the previous works for the case of particle fluid passing a square block in a two dimensional channel flow. The results show that the dispersion of particles in three different square pore structures are much different, and vary with Stokes numbers for the same square pore even the Reynolds numbers are the same. In addition, the number and the position of deposited particles are analyzed. It shows that the deposition characteristics of each wall are mainly influenced by Stokes number, Reynolds number and the pore structure.
The Stokoe resonant column apparatus: effects of stiffness, mass and specimen fixity

This paper reports the results of a series of analyses, and physical and numerical experiments, carried out in order to investigate the effects of apparatus stiffness and mass, and specimen fixity, on the results obtained from fixed–free resonant column testing. It is shown that the stiffness of the drive head and the mass of the apparatus base can both have a significant effect on the results obtained from tests on stiffer geomaterials. Connectivity between the specimen, the apparatus base and the top cap is also an issue. Methods of recognising and determining the magnitudes of these effects are described, and recommendations are made for their evaluation and control.
Pyrotinib sensitizes 5‑fluorouracil‑resistant HER2-positive breast cancer cells to 5‑fluorouracil

BACKGROUND: Clinical trials have shown that pyrotinib+ capecitabine significantly improved efficacy of patients with human epidermal growth factor receptor 2(HER2) +breast cancer. However, whether pyrotinib sensitizes 5‑Fluorouracil(5‑FU)‑resistant breast cancer cells to 5‑FU is unknown. This study aimed to investigate the effects of pyrotinib on HER2+breast cancer cells with resistance to 5‑FU and provide new clues for the pyrotinib treatment in 5-FU-resistant breast cancer.METHODS: the 5‑FU‑resistant breast cancer cell lines SK-BR-3/FU and MAD-MB-453/FU were established by continuous exposure of the parental cells to 5‑FU.The effects of pyrotinib on these cell lines were examined by growth inhibitory activity assay, reverse transcription‑quantitative polymerase chain reaction, Western blot analysis, high-performance liquid chromatography and animal experiments.RESULTS: Pyrotinib inhibited the proliferation of 5-FU-resistant and parental HER2-positive breast cancer cells and re-sensitized resistant cells to 5-FU by decreasing the expression of thymidylate synthase(TS) and ABC transporter subfamily G member 2(ABCG2). In a xenograft model, combination treatment with 5-FU and pyrotinib showed greater antitumor activity than either agent alone. CONCLUSIONS: Our results offer a preclinical rationale for clinical investigations of combination treatment with pyrotinib and 5-FU for 5-FU-resistant HER2-positive breast cancer.
A study on the relaxation behavior of fabric's crease recovery angle

On the basis of Viscoelasticity Theory of textile materials, the Maxwell's Model, Kalvin Paunting Model and Burger's model were analyzed in the paper. The regression equation of the strain relaxation curve was established and the experiments verify that the crease recovery angle can be predicted by the regression equation of Burger's model. The relaxation behavior of crease recovery angle varying with time was according to the creep‐relaxation equation.
Antibacterial activity and characterisation of some Egyptian honey of different floral origin

The aim of the current study was to evaluate the antibacterial activity and to analyse the physicochemical properties of some Egyptian honey of different botanical origin in comparison with Manuka honey from New Zealand. Antibacterial activity of Egyptian honey of different floral origin was evaluated against five reference bacterial strains including both Gram-positive and Gram-negative bacteria using well diffusion method. Pollen analysis was used to confirm the floral origin of honey. Meanwhile, the physicochemical parameters including total phenolic and total flavonoid contents were measured to assess the quality of honey. Some honey types including Flowers, Aashab, Bardakosh, and Black seed honey showed significant antibacterial activity against Staphylococcus aureus (ATCC 25923) when compared with clindamycin. The same types of honey, except Black seed honey exhibited significant antibacterial activity against Citrobacter diversus (ATCC 13315). The total phenolic and total flavonoid contents ranged from 130.5±9.0 to 175.3±11.3 mg GAE/100 g honey and 22.3±1.7–30.9±2.6 mg RE/100 g honey, respectively. The results indicated that Egyptian honey is a promising natural product that can be potentially used as an alternative to synthetic antibiotics. Authentication of honey through the investigation of its physicochemical characteristics is a very important determinant of its biological activity. Separation and investigation of the antimicrobial activity of each of the active compounds of honey will provide more information on the efficacy and the mechanism of its biological activity. Further studies are still needed to identify and standardise protocols for the use of honey either in the protection against or the treatment of microbial infections.
Dynamic torsional response analysis of mechanoluminescent paint and its application to non-contacting automotive torque transducers

This paper presents the result of a preliminary experimental study on the dynamic torsional response analysis of mechanoluminescent (ML) paint for potential development as a new type of non-contacting torque transducer. The torsional torque applied to a transmission shaft is measured by sensing the ML intensity emitting from an ML paint coating a transmission shaft. This study provides the fundamental knowledge for the development of new non-contacting torque sensing technology based on the ML intensity detection. The proposed measurement principle appears to offer potential applications in automotive torque measurement systems, even though the loading rate-dependent characteristics of the ML intensity needs to be examined further.
SINGLE-EVENT CRACKING TEMPERATURE OF ASPHALT PAVEMENTS DIRECTLY FROM BENDING BEAM RHEOMETER DATA

Asphalt pavements under low temperature conditions develop transverse cracks as a result of one or a combination of three distress mechanisms: (1) single-event thermal cracking; (2) thermal fatigue; and (3) load-associated thermal cracking. The cracking temperature of asphalt pavements based on the single-event thermal cracking mechanism of the asphalt binder has been suggested as a good measure of the low temperature criterion for use as a binder purchase specification. The determination of the single-event cracking temperature \iT\Dcr\N requires a comparison of the pavement thermal stress computed from the binder stiffness data generated from the bending beam rheometer (BBR) with the binder strength data measured using the direct tension test (DTT). Thus, two instruments, each with different sample preparation techniques, different sample sizes, and different data analysis methods, are required for the final determination of a single point signifying the cracking temperature. The present work revisits the method of data analysis to determine \iT\Dcr\N and shows that the cracking temperature can be obtained directly from the BBR data without the use of DTT. The procedure uses the pavement thermal stress computed form the BBR binder stiffness data to calculate the intersection of the two asymptotic thermal stress buildup rates, which directly identifies the cracking temperature. This procedure has a significant advantage in that it makes the BBR a stand-alone device for the determination of the low temperature binder specifications.
Prevalence of violence and associated factors among youth in Northwest Ethiopia: Community-based cross-sectional study

Background Violence as a known serious public health problem affects people in all stages of life, from childhood to the elderly. In society, one of the most visible forms of violence is young people violence, whereas they, adolescents and young adults, are the main victims of such violence. There was limited information on the burden of violence and factors among this age group. Therefore, this study aimed to determine the prevalence of violence and its associated factors among youth in Northwest, Ethiopia. Methods A community-based cross-sectional study design was conducted to estimate the magnitude of violence among youth in Northwest, Ethiopia. Data were taken from the mega project entitled assessment of common health problem and risky health behavior among youth. Youth violence was the dependent variable whereas the socio-demographic variables and substance use were the independent-variables. The bivariate logistic regression model was employed to identify associated factors. An adjusted odds ratio with a 95% confidence interval was used to determine factors associated with violence. Results From the total 1765 representatives of the youth population,1597 (90.5%) youth participated in the study. Overall, the prevalence of violence among youth aged 15–24 years for the last 12 months was 21.5%. In the multivariable logistic regression model, factors significantly associated with violence were being married and divorced (AOR = 1.77, 95%CI: 1.13, 2.79) and (AOR = 5.67, 95%CI: 2.93, 10.99), respectively, living with mother’s only (AOR = 1.85,95%CI: 1.28, 2.66) and father’s only (AOR = 2.45, 95% CI: 1.30, 4.63), and substance use (AOR = 2.38,95% CI: 1.56, 3.66). Conclusions The prevalence of violence among youth was high compared to other studies. Special emphasis Should be given for youth violence in order to manage the victims as well as for preventing and controlling the identified factors through strengthening policies and strategies.
Women, construction and health and safety (H&S): South African and Tanzanian perspectives

Construction by its very nature constitutes a challenge in terms of health and safety (HS their role; their capacity; their impact; their potential contribution; barriers to their participation; and general and gender specific issues. The paper reports on studies conducted in South Africa and Tanzania, the salient findings being: women have a role in construction; increased participation by women will contribute to improving the image of construction; women have requirements related to their gender and roles; some construction materials constitute a manual materials handling problem to women, and current welfare facilities for women (such as medical support or child care) are inadequate. The paper concludes that endeavours are necessary to change attitudes, promote participation by women, accommodate women, and improve conditions, particularly H&S.
Protection and Guidance of Downstream Moving Fish with Electrified Horizontal Bar Rack Bypass Systems

Horizontal bar rack bypass systems (HBR-BS) are characterized by a horizontal bar rack (HBR) with narrow clear bar spacing of 10–20 mm and an adjacent bypass (BS) to efficiently protect and guide downstream moving fish at water intakes. The small bar spacing may lead to operational challenges, such as clogging and high head losses. This study investigated whether combining an HBR with a low-voltage electric field (e-HBR) allows one to increase the clear bar spacing while maintaining a high standard of fish protection and guidance efficiency. To this end, an HBR-BS with 20 mm bar spacing and an e-HBR-BS with 20 and 51 mm bar spacing were tested with spirlin (Alburnoides bipunctatus) and European eel (Anguilla anguilla) in a laboratory flume. The racks were electrified with 38 V pulsed direct current. The protection efficiency of the e-HBR with 51 mm was 96% for spirlin and 86% for eels, which are similar results to those of the HBR with 20 mm. Some eels passed through the e-HBR, but only when they were parallel to the rack. Fish injuries of variable severeness due to the electrification were observed. The results highlight the potential of hybrid barriers for the protection of downstream moving fish. However, fish injuries due to electricity may occur; and reporting applied voltage, electrode geometry, resulting electric field strength and the pulse pattern of the electrified rack setup is necessary to ensure comparability among studies and to avoid injuries.
Complete mitochondrial genome of Sinocyclocheilus yishanensis (Cypriniformes: Cyprinidae) and phylogenetic position

Abstract Sinocyclocheilus yishanensis belongs to the genus Sinocyclucheilus (Cypriniformes, Cyprinidae), endemic to Guangxi province, Southwestern China. The circular mitogenome was 16,573 bp in length and consisted of 13 protein-coding genes, two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and one non-coding control region. The overall base composition was 31.83% A, 25.14% T, 27.03% C, and 16.00% G with 43.03% GC content. Phylogenetic analysis using mitochondrial genomes of 16 species showed that all Sinocyclocheilus species clustered as one monophyletic clade except S. jii, and S. yishanensis was the closest to S. ronganensis.
Evolution des précipitations extrêmes en France en contexte de changement climatique

Cette communication présente une synthèse des travaux menés dans le cadre du projet ANR/Extraflo sur l'évolution des extrêmes pluviométriques en France au pas de temps journalier et infra-quotidien s'appuyant sur un jeu de données étendu de plus de 900 séries. Il a été montré qu'une majorité de séries présentait une tendance à la hausse non significative notamment en région Méditerranéenne, liée à l'occurrence de plusieurs années récentes présentant des évènements extrêmes exceptionnels par rapport au reste de l'échantillon. Une piste intéressante pour caractériser ces évolutions consiste à identifier des co-variables climatiques (types de temps associés aux pluies intenses, températures moyennes, flux d'humidité) et les prendre en compte avec un modèle POT non stationnaire en climat présent ou futur. L'application de cette méthode avec des projections climatiques sous scénario A2 du GIEC laisse envisager une hausse possible des différents quantiles à l'horizon 2070.
Planar antenna for continuous beam scanning and broadside radiation by selective surface wave suppression

A printed leaky-wave antenna (LWA) based on a grating of concentric annular microstrip rings fed by a non-directive TM0 surface-wave launcher (SWL) is presented for two-sided continuous beam scanning and broadside radiation. By appropriate selection of the grating periodicity TE field distributions can be suppressed over a large bandwidth ensuring efficient TM0 leakage and radiation into the far field. Measured results demonstrate a pencil beam at broadside with a 3 dB beamwidth less than 6° at 17.9 GHz. The presented LWA may be useful for radar and surveillance systems where continuous beam scanning through broadside is desired.
Impact of sequence-dependent setup time on job shop scheduling performance

In a production system using multi-purpose and flexible machines, reducing setup time is an important task for better shop performance. Numerous cases were reported about successful reduction of setup times by standardization of setup procedures. However, setup times have not been eliminated and remain an important element of real production problems for production systems such as commercial printing, plastics manufacturing, metal processing, etc. It is especially critical when the setup time is sequence dependent. In this situation, shop performance cannot be effectively improved without the aid of an appropriate scheduling procedure. Review of the past studies shows that there has not been a significant amount of research done on the scheduling procedure for a dynamic job shop with sequence dependent setup times. This paper investigates the job shop scheduling problems that are complicated by sequence-dependent setup times. The study classifies and tests scheduling rules by considering whether setup tim.
Agricultural Productivity Trends in India: Sustainability Issues

The sustainability issue of the crop productivity is fast emerging. The post-Green Revolution phase is characterized by high input-use and decelerating total factor productivity growth (TFPG). The agricultural productivity attained during the 1980s has not been sustained during the 1990s and has posed a challenge for the researchers to shift the production function upward by improving the technology index. It calls for an examination of issues related to the trends in the agricultural productivity, particularly with reference to individual crops grown in the major states of India. Temporal and spatial variations of TFPG for major crops of India have also been examined.
Extensive Experimental Study of Circumferential Single Groove in an Axial Flow Compressor

Circumferential single-groove casing treatment becomes an interesting topic in recent few years, because it is a good tool to explore the interaction between the groove and the flow in blade tip region. The stall margin improvement (SMI) as a function of the axial groove location has been found for some compressors, such a trend cannot be predicted by steady high-fidelity CFD simulations. Recent efforts show that to catch such a trend, multi-passage, unsteady flow simulations are needed as the stalling mechanism itself involves cross-passage flows and unsteady dynamics. This indicates a need to validate unsteady numerical simulation results. In this paper, an extensive experimental study of a total of fifteen single casing grooves in a low-speed axial compressor rotor is presented, the groove location varies from 0.4% to 98.3% of axial tip chord are tested. The unsteady pressure data both at casing and at the blade wake with different groove locations are measured and processed, including the movement of trajectory of tip leakage flow, the evolution of unsteadiness of tip leakage flow (UTLF), the unsteady spectrum signature during the stall process, and the outlet unsteady flow characteristic along the span. These data provide a case study for validation of the unsteady CFD results, and may be helpful for further interpretation on the stalling mechanism affected by circumferential casing grooves. © 2014 ASME
Understandings of occupational health and safety risk control in small business construction firms: barriers to implementing technological controls

The construction industry poses a particular challenge for the making of occupational health and safety (OHS) risk control decisions which are equitable to all parties involved in the construction process. Typically, small business construction firms are engaged as subcontractors in the construction industry and are located at the lower end of the inter-organizational hierarchy in a construction project. As such, their ability to exert an influence on decision-making in the construction process is limited, despite their employees' day to day exposure to OHS risks. A qualitative study of understandings of OHS risk control was conducted among a sample of small businesses engaged in the Australian construction industry. Two OHS risks relevant to the construction industry were selected for study. One risk (falls from height) represented an immediate consequence while the other (occupational skin disease) represented a long-term health effect. Understandings of control for these OHS risks were explored during in-depth interviews. The results suggest that, at the small business end of the industry, there is a fatalistic resignation to OHS risks being an unavoidable part of the job. This leads to an emphasis on individual rather than technological controls for OHS risk. The implication of these findings for the effective management of OHS risk is discussed.
Modeling of the Anode Crater Formation in Electrical Discharge Machining

This research presents a numerical model and the experimental validation of the anode crater formation in electrical discharge machining (EDM) process. The modeling is based on the theory that the material removal process in EDM is composed of two consecutive phases: the plasma heating phase in which intensive thermal energy density is applied locally to melt the work-material and the bubble collapsing phase in which the fluidic impact expels the molten material. A mathematical heat source model with Gaussian distributed heat flux and time variant heating area is applied in the plasma heating phase. Standard modules of a commercial computational fluid dynamics software, FLUENT, are adapted to model the crater formation in EDM. The material melting is simulated using transient heat transfer analysis and an enthalpy balance method. The volume of fraction (VOF) method is used to tackle the multiphase interactions in the processes of bubble compression and collapsing and molten material splashing and resolidification. Crater and debris geometries are attained from the model simulation and validation experiments are conducted to compare the crater morphology. The simulation and experiment results at different discharge conditions show good agreement on crater diameter suggest that the model is able to describe the mechanism of EDM crater formation.

Evaluation of Runoff and Erosion Models

Runoff and sediment yield for 30 runoff events on three experimental watersheds are calculated using the agricultural non–point-source pollution model (AGNPS), areal non–point-source watershed environmental response simulation (ANSWERS), and chemicals runoff and erosion from agricultural management systems (CREAMS) runoff-erossion models. The results are compared with measured runoff and sediment yield. The computed and measured runoffs show reasonable to poor agreement. The average ratios of computed to measured sediment yields for the various storms and watersheds show a large scatter. ANSWERS provides the most consistent results for estimates of runoff and sediment yield. All three models tend to underestimate sediment yield for large storms. For high intensity and low intensity storms on two small watersheds, the detachment models in ANSWERS and CREAMS have biases (ratio of calculated to measured sediment yields) that range between 0.9–1.0 and 0.4–1.6, respectively.
