Inter-agency governance risk in managing hospital responses to extreme weather events in New South Wales, Australia: a facilities management perspective of shared situational awareness

Extreme weather is predicted to become more frequent and severe into the future. While our understanding of hospital infrastructure vulnerability to such events has advanced considerably in recent years, current approaches to healthcare facilities management treat hospitals in isolation from their surrounding governance infrastructure. However, recent research indicates that if hospital resilience is to be properly understood, health infrastructure must be managed holistically, as part of a much larger governance system of interdependent organizations. The inter-agency governance risks associated with this system are currently ignored in the facilities management literature. To explore these risks, an in-depth case study of 24 agencies in the state of New South Wales, Australia is presented. The results show that facilities managers are embedded in a highly complex and dynamic array of governance boundaries which are largely unresolved and misunderstood. A number of practical strategies are presented which could be adopted to significantly improve facilities manager’s integration into this system. These include: mapping hospital dependency on other agencies to build surge capacity; resolving overlapping operational boundaries with other agencies; proactive risk reduction for critical external support infrastructure; understanding potential conflicts with the objectives external agencies in responding to an extreme weather event.

This book treats the vibrations of structures with a sequence of structural models: first, discrete elements such as spring and masses; then, continuous elements such as beams and plates; and finally, simple structures using finite elements and the method of substructures
Influences of timing of liver abscess control and early metabolizable amino acid supplementation on feedlot growth-performance and digestive function of calf-fed Holstein steers

ABSTRACT Objective Our objective was to examine the influence of timing of liver abscess control and early rumen-protected AA supplementation on cattle growth performance (Exp. 1) and digestive function (Exp. 2), and related responses on liver abscess incidence and AA supply to the small intestine of feedlot steers. Materials and Methods In Exp. 1, a total of 200 calves were used in a 321-d experiment. Four strategies for liver abscess control using virginiamycin (VM; 16 mg of VM/kg of diet DM, Phibro Animal Health) were used: (1) 0% VM; (2) VM supplementation during the initial 168 d; (3) VM supplementation during the final 153 d; and (4) VM supplemented continuously for 321 d. During the initial 168-d feeding period, 2 levels of rumen-protected Met and Lys (Smartamine ML: SML; 0 vs. 0.6% DM basis, Adisseo) were supplemented across VM treatments in a 2 × 4 factorial arrangement. In Exp. 2, 4 Holstein steers (382 ± 23 kg) with cannulas in the rumen and proximal duodenum were used in a 4 × 4 Latin square design to evaluate treatment effects on digestion. Results and Discussion Cattle growth performance was not affected (P ≥ 0.18) by VM supplementation strategy. Moreover, VM supplementation did not affect (P ≥ 0.10) carcass characteristics. Liver abscess incidence was low (4%) and not affected (P ≥ 0.62) by supplementation strategy. Supplemental VM did not affect characteristics of ruminal and total-tract digestion (P ≥ 0.27). Supplementation of SML during the first 168 d decreased (P = 0.02) DMI during the last 153 d of the experiment, and tended to decrease (P = 0.07) overall (321-d) DMI. Smartamine ML supplementation did not affect (P ≥ 0.11) ADG, G:F, carcass characteristics, percentage of abscessed liver, or characteristics of ruminal and total-tract digestion. Implications and Applications Timing of VM supplementation did not influence cattle growth performance or incidence of liver abscess, which was low (4%) regardless of VM treatment. Protected Met and Lys supplementation increased Met or Lys supply to the small intestine. However, MP and AA supplies of the basal diet, alone, were apparently adequate to achieve expected growth performance.
Silicon Integrated Optics: Fabrication and Characterization

For decades, the microelectronics industry has sought integration and miniaturization as canonized in Moore's Law, and has continued doubling transistor density about every two years. However, further miniaturization of circuit elements is creating a bandwidth problem as chip interconnect wires shrink as well. A potential solution is the creation of an on-chip optical network with low delays that would be impossible to achieve using metal buses. However, this technology requires integrating optics with silicon microelectronics. The lack of efficient silicon optical sources has stymied efforts of an all-Si optical platform. Instead, the integration of efficient emitter materials, such as III-V semiconductors, with Si photonic structures is a low-cost, CMOS-compatible alternative platform. This thesis focuses on making and measuring on-chip photonic structures suitable for on-chip optical networking. The first part of the thesis assesses processing techniques of silicon and other semiconductor materials. Plasmas for etching and surface modification are described and used to make bonded, hybrid Si/III-V structures. Additionally, a novel masking method using gallium implantation into silicon for pattern definition is characterized. The second part of the thesis focuses on demonstrations of fabricated optical structures. A dense array of silicon devices is measured, consisting of fully-etched grating couplers, low-loss waveguides and ring resonators. Finally, recent progress in the Si/III-V hybrid system is discussed. Supermode control of devices is described, which uses changing Si waveguide width to control modal overlap with the gain material. Hybrid Si/III-V, Fabry-Perot evanescent lasers are demonstrated, utilizing a CMOS-compatible process suitable for integration on in electronics platforms. Future prospects and ultimate limits of Si devices and the hybrid Si/III-V system are also considered.
Measured electromagnetic shielding performance of commonly used cables and connectors

The intrinsic electromagnetic property of a cable or connector shield is considered its surface transfer impedance. This is the ratio of the longitudinal open circuit voltage measured on one side of the shield (normally the inside) to the axial current on the other side (normally the outside). In cases where a high electric field is present at the surface of the shield, the transfer admittance or charge transfer elastance is also important. Measurements of typical cables, connectors, backshells, and cable terminations are presented and explained in terms of simple models. >
The electromagnetic properties of re-entrant dielectric honeycombs

Dielectric honeycombs are cellular materials often used in applications that require structural and electromagnetic characteristics, e.g., in LO (low observable) and radome components. A re-entrant (or auxetic) honeycomb is a cellular material with structural properties that are superior to those of a conventional honeycomb. By employing the finite-difference time-domain (FDTD) technique with periodic boundary conditions, the electromagnetic properties of re-entrant honeycombs are determined and compared to those of a conventional honeycomb. Re-entrant honeycombs are shown to have substantially superior electromagnetic properties. Measured permittivity data are used to substantiate the conclusions based on predicted FDTD data. The use of re-entrant honeycombs, rather than conventional honeycombs, in LO and radome applications can yield improved structural and electromagnetic performance.
Sustainable Reuse of Dredged Soil as a Substrate Material by Improvement with Polyacrylamide, Straw, and Superabsorbent Polymer

Every year, a significant quantity of dredged soil is generated as a result of channel dredging operations. However, there is relatively little evidence available regarding the sustainable reuse of dredged soils. In this study, an improved substrate material mainly composed of dredged soil was developed to examine the effects of three substrate amendments on the soil’s nutritional content, physical properties, and water retention capacity, as well as the germination rate of tall fescue. The orthogonal combination of the three substrates was controlled in a pot experiment using polyacrylamide (PAM), rice straw, and superabsorbent polymer (SAP) at application rates of 0.5, 1, 1.5, 2, and 2.5 g/kg; 15, 20, 25, 30, and 35 g/kg; and 0, 3, 6, 9, and 12 g/kg, respectively. The results showed that adequate application of PAM may improve the water retention capacity and available N retention capacity of dredged soil. PAM inhibited tall fescue germination significantly when the concentration exceeded 0.5 g/kg ( p < 0.05). The addition of rice straw significantly improved the nutritional content of dredging soil and the germination rate of tall fescue ( p < 0.05). Increased SAP significantly decreased the bulk density of dredged soil ( p < 0.05). The lowest test group was 48.20% less than CK. This study offers novel ideas for the sustainable reuse of dredged soil and serves as a guide for future research aimed at increasing the effectiveness of external-soil spray seeding technologies.
Performance analysis of a conventional PV/T mixed mode dryer under no load condition

A solar dryer integrated with photovoltaic powered DC fan has been designed and installed at Solar Energy Park, Indian Institute of Technology Delhi. The dryer has been coupled to a solar air heater having blackened surface of absorber for improved energy collection efficiency and a drying chamber with chimney. An analytical expression for characteristic equation for photovoltaic/thermal mixed mode dryer has been derived as a function of design and climatic parameters. The experiment was carried out for forced mode under no load conditions during April 2008 and validated with theoretical results for New Delhi climatic condition.
Immunoseroproteomic profiling in autoantibody to ENO1 as potential biomarker in immunodiagnosis of osteosarcoma by serological proteome analysis (SERPA) approach

ABSTRACT Osteosarcoma (OS) is the most common highly malignant primary solid bone tumor. Despite its relatively low incidence among cancers, it remains one of the most harmful primary malignant tumors in childhood and adolescence. It is now evident that serum autoantibodies against tumor-associated antigens (TAAs) could be used as serological cancer biomarkers in types of cancers. Serological proteome analysis (SERPA) approach was applied to profile anti-TAA autoantibody response in sera from patients with OS and normal human, as well as explore difference between this response. This approach can detect autoantibodies that could serve as clinical biomarkers and immunotherapeutic agents. Enzyme-linked immunosorbent assay (ELISA) and Western blotting were further used to validate the level of identified TAAs. ENO1 as a 47kD TAA in OS was identified and characterized by SERPA. Analysis of 172 serum samples with OS, osteochondroma (OC), and normal human sera (NHS) by ELISA showed higher frequency of anti-ENO1 autoantibodies in OS sera compared to others. Interestingly, decrease of ENO1 immunoreactivity was observed in most patients after treatments, which may imply a potential association between anti-ENO1 autoantibody titers and disease progression. Nine of twelve sera reacted strongly against purified ENO1, but three reacted weakly against purified ENO1, which indicated 75.0% sera with positive optimal density values from ELISA were consistently positive in Western blotting. The expression of ENO1 in OS tissues was evaluated by immunohistochemistry in tumor microarray. ENO1 was one of the autoantibodies that elicit autoimmune responses in OS and can be used as biomarkers in immunodiagnosis and progression of OS.
Mechanisms of collateral damage: heterospecific neighbor density mediates parasitism by eavesdroppers on hourglass treefrogs

Males often broadcast conspicuous signals from within mixed-species aggregations to attract mates. In addition to attracting females, however, these displays expose signalers to eavesdropping predators and parasites. For individuals in mixed-species aggregations, the balance between attracting mates and avoiding eavesdroppers is influenced both by the attractiveness of their calls and by the calling activity of conspecific and heterospecific neighbors. Through a process termed “collateral damage”, frogs signaling near heterospecific neighbors that are highly attractive to eavesdroppers can experience drastically increased parasitism compared to those signaling next to conspecifics. Here, we investigate whether the intensity of this collateral damage is influenced by the density of, or the call types produced by, heterospecific neighbors. In phonotaxis trials using hourglass treefrogs as the focal species and túngara frogs as the attractive heterospecific neighbor, we found no differences in the number of parasites attracted to hourglass treefrog calls played adjacent to simple versus complex túngara calls. By contrast, a higher density of neighboring túngara frogs decreased the collateral damage suffered by hourglass treefrogs by approximately 40%. Our results demonstrate that the density of nearby heterospecifics can modulate parasitism risk due to collateral damage in mixed-species aggregations. Thus, our conception of the dilution of eavesdropper risks with increasing group size may need to be augmented to include the effects of multiple prey or host types. HIGHLIGHTS ● Heterospecific call type does not change collateral damage on hourglass treefrogs ● However, parasitism decreases when calling next to high densities of heterospecifics
Relationship between Drought and Precipitation Heterogeneity: An Analysis across Rain-Fed Agricultural Regions in Eastern Gansu, China

Based on daily meteorological data from 55 meteorological stations in eastern Gansu from 1960 to 2017, the characteristics of the drought process and precipitation heterogeneity were analyzed, and the relationship between drought and precipitation heterogeneity was evaluated. Results showed that there were 1–3 drought processes in the study area every year. Drought processes in the eastern and north-central regions were more frequent than those in other regions. Droughts were mainly manifested as intra-seasonal droughts, especially across the spring and summer. PCD (Precipitation Concentration Degree, the concentration degree of the precipitation at a certain time) ranged from 0.2 to 0.7 in the area. PCD increased in spring and autumn but decreased in summer and winter for most regions from 1960 to 2017. PCP (Precipitation Concentration Period, the shortest time which the precipitation was concentrated in) was from late April to early May in spring, mid-to-late July in summer, mid-September in autumn, and late January in winter. In the last 58 years, PCP has remained consistent in most regions, varying by approximately 10 days. In addition to insignificant changes in winter, the days with light and moderate rain presented a declining trend, especially in summer and autumn. The larger the PCD, the fewer the days with light and moderate rain, and the stronger the drought intensity. However, in the east-central region, the larger the PCD in autumn, the weaker was the drought intensity. This difference is related to the PCP and the evapotranspiration. Additionally, the later the PCP, the stronger was the drought intensity, particularly in summer and autumn. When PCD was ≥0.5 in spring and ≥0.4 in summer, the PCP was after May and August in spring and summer, respectively. Droughts appeared in 28–56% of periods when seasonal precipitation was above normal. When PCD was ≥0.5 in autumn and PCP was in early and middle September, droughts appeared in 7% of periods when precipitation was above normal. Our results show that although less precipitation is the leading influencing factor of drought in the dry rain-fed agricultural areas, the influence of precipitation heterogeneity should be also considered for the prediction and diagnosis of seasonal drought.
Analysis of the observed seismic response of a highway bridge

Strong-motion accelerograms obtained on the San Juan Bautista 156/101 Separation Bridge during the 6 August 1979 Coyote Lake, California, earthquake are used to examine the response of this multiple-span bridge to moderate levels of earthquake loading. Although the bridge was not damaged, the records are of significant engineering interest as they are the first to be recorded on a highway bridge structure in North America. A technique of system identification is used to determine optimal modal parameters for linear models which can closely replicate the observed time-domain seismic response of the bridge. Time variations in frequency and damping in the horizontal response are identified using a moving-window analysis. A three-dimensional finite element model is developed to study the bridge response in detail. The first two horizontal modal frequencies computed from this model are in excellent agreement with information obtained during the system identification analysis provided the finite element model's expansion joints are locked, preventing relative translational motions from occurring across the joints. Locking is confirmed by the observed seismic deformations of the structure in the fundamental mode. Fundamental vertical frequencies of the individual spans, predicted by the finite element model, are in very good agreement with ambient vibration test data.
Event-based controller to avoid deadlock and collisions in zone-control AGVS

Automated Guided Vehicle Systems (AGVSs) are the most flexible means to transport pieces among workstations of an Automated Manufacturing System (AMS). The traffic control of such systems must be in charge of avoiding collisions and deadlock conditions. This paper formulates a zone-control scheme to face this problem in real time, based of the knowledge of the AGVS operative conditions. Starting from some theoretical results already stated in the context of deadlock avoidance in AMS, some algorithms are proposed to control, in real time, path assignments to the vehicles and their moves from zone to zone in the system. A final discussion compares the proposed approach with other methods offered by the recent literature.
A current flow controller for use in HVDC grids

Early proposals for multi-terminal HVDC interconnections have been predominantly radial type connections, that is, between any two nodes there is only one branch. However, plans for `HVDC Grids' in the not too distant future are, or include, meshed sections where there are parallel branches between nodes in the HVDC Grid. In such meshed HVDC Grid the DC current will inherently flow from one node to another via the path of least resistance. However, this may mean that one branch within the HVDC Grid becomes overloaded, hence, power flows across the HVDC Grid may have be constrained in order to keep all branch loadings within their rating. In order to avoid the need to apply constraints a number of solutions have been proposed to date and these are discussed here. (5 pages)
Comparison of the Mode of Delivery between COVID and Non-COVID Pregnancies

Background: The pregnant women and the newborn infants represent the vulnerable population in every society. Therefore Improvement efforts for the survival and the well being of the mothers and the neonates is indisputably a global priority especially during this pandemic of severe acute respiratory syndrome caused by a novel corona virus, called Covid-19. declared by the WHO ( World Health Association ) as global pandemic on March 11,2020. This pandemic has significantly altered the life styles of the pregnant women, boosting their apprehensions and concerns and importing great impacts on their health management. Current evidence suggests that the pregnant women are not at increased risk of Covid -19 as compared to the other adults. Similarly the condition is not severe in them. At the place of the current study the mode of delivery of the Covid patients is individualized and based on severity of the Covid infection and purely on the obstetric indications, as the evidence suggests that no mode of delivery is superior in terms of prevention of the vertical transmission. Objective: We performed this study to compare the mode of delivery between the pregnant Covid and the non Covid pregnant population with the null hypothesis that the Covid effected pregnant patients are more prone to have caesarean section as compared to non Covid pregnant females and they are more prone to have CTG (cardiotocographic) abnormalities. Material and Methods: It was a retrospective observational study done to compare the mode of delivery and the rate of CTG abnormalities in the study and the control group as the primary outcome. The secondary outcome was duration of active phase of the first stage, second and third stage of the labour between the pregnant Covid and the non Covid pregnant population for a period of 6 months (First January 2021 -30th June 2021) in labor ward of Dr. Sulaiman Al-Habib Hospital, Sweidi, Riyadh, Saudi Arabia. The study population comprised of 100 pregnant patients meeting our inclusion and exclusion criteria. The number of patients in each group was equal. Results: No statistically significant difference was observed in the age, parity and ethnicity of both the groups. The rate of caesarean section was 38% (n=19) in the Covid group while in the control group it was 10% (n=05), the difference is statistically significant as shown by the P-Value of 0.004. No significant difference in the CTG abnormalities was found in both the groups. However statistically significant reduction in the active phase of the first, second and third stage of labour was noted in the study population. Conclusion: We hereby prove our null hypothesis that the Covid-19 effected pregnant patients are prone to have higher caesarean section rate, however no difference in rate of CTG (cardiotocographic) abnormalities was observed in both the groups. Significant reduction in the duration of all stages of the labour was also noticed which is a fruit of thought for the upcoming research. Key words: Pregnancy, labour, caesarean section, Covid-19, duration of labour.
Ferro-Electric Fast Reactive Tuner Applications for SRF Cavities

A Ferro-Electric fast Reactive Tuner (FE-FRT) is a novel type of RF cavity tuner containing a low loss ferroelectric material. FE-FRTs have no moving parts and allow cavity frequencies to be changed extremely quickly (on the timescale of 100 s of ns or less). They are of particular interest for SRF cavities as they can be placed outside the liquid helium environment and without an FE-FRT it’s typically very difficult to tune SRF cavities quickly. FE-FRTs can be used for a wide variety of use cases including microphonics suppression, RF switching, and transient beam loading compensation. This promises entirely new operational capabilities, increased performance and cost savings for a variety of existing and proposed accelerators. An overview of the theory and potential applications will be discussed in detail.
