Abstract:
AbstractIn this paper a new method for the removal of gypsum degradation layers from carbonatic matrices in cultural heritage conservation, using aqueous Highly Viscous Polymeric Dispersions (HVPDs) based on partially hydrolyzed poly(vinyl acetate) and borax, embedded with chelators, is presented. Due to their interesting viscoelasticity, these systems guarantee a good adhesion to the treated surface and easiness of removal in one step, minimizing the residues. Thus, they can potentially overcome the “residue question” limit associated to traditional methodologies that use thickened solutions of chelators. Here the rheological properties of HVPDs containing different amounts of selected chelating agents are explored and their efficacy in the extraction of gypsum is verified through cleaning tests onto artificially sulfated travertine tiles. The homogeneous removal of gypsum across the surface was checked non-invasively via Fourier Transform Infrared Spectroscopy (FTIR) 2D Imaging. An analytical protocol for the pre-treatment and the analysis of HVPD samples by means of Ion Cromatography (IC) and Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) was set up and the approximate amount of calcium sulfate removed was determined.

Abstract:
BACKGROUND: Transcutaneous electrical nerve stimulation (TENS) is one of the most common methods for managing shoulder pain, and high voltage pulsed currents (HVPS) may be used for reducing pain. However, their immediate effects on resting pain and pain-free active range of shoulder motion (pfROM) in patients with subacromial pain syndrome (SAPS) have not been studied comparatively, yet. OBJECTIVES: The aim of this study was to compare the immediate effects of TENS, HVPS and placebo stimulation on shoulder resting pain and pfROM in patients with SAPS. METHODS: Randomized, placebo-controlled, double-blind, crossover study. One hundred and six patients with SAPS received placebo (predetermined 1st day application), TENS and HVPS with 1-day interval, in a random sequence. Before and after each application, resting pain and pfROM were evaluated by 0–10 cm visual analogue scales and a digital inclinometer, respectively. RESULTS: Intensity of pain decreased significantly after TENS, HVPS and placebo interventions (p< 0.05). While pfROMs increased significantly after TENS and HVPS (p< 0.05), remained unchanged after placebo, except for internal and external rotations (p> 0.05). The most obvious effects on pain and pfROMs occurred after HVPS (p< 0.05). CONCLUSION: In patients with SAPS, both HVPS and TENS, but preferably HVPS can be used effectively to decrease pain and increase pfROM.

Studies on vancomycin pharmacokinetics in acute kidney injury (AKI) patients on high-volume peritoneal dialysis (HVPD) are lacking. We studied the pharmacokinetics of intravenous (IV) vancomycin in AKI patients treated by HVPD who received a prescribed single IV dose of vancomycin (15 - 20 mg/kg total body weight) to determine the extent of vancomycin removal and to establish vancomycin dosing guidelines for the empirical treatment of AKI patients receiving HVPD. The application of 18 mg/kg vancomycin every 48 - 72 hours in AKI patients undergoing HVPD was required to maintain therapeutic concentrations.

Abstract:
Abstract Purpose While 10–20% of heavy vehicle crashes (HVDs) are drowsiness-related, the contributions of subsequent shifts to chronic drowsiness in HVDs is largely unknown. Eye-blink parameters indicate driver drowsiness reliably. This study examined the association of consecutive shifts and real-time drowsiness in HVDs. Methods Habitual sleep-wake of HVDs (all males, aged 49.5 ± 8 years) was monitored objectively (Philips Actiwatch, N=15) for 5 weeks (5.75± 1.4 hours). Johns Drowsiness Score (JDS, a composite eye-blink parameter in one-min intervals) was monitored for 4 weeks in HVDs (N=14) using an infrared oculography (Optalert, Melbourne, Australia) device. We assessed the association of drowsiness events (JDS equal or larger than 2.6) with consecutive shift types via mixed linear regression models. Results Eigth consecutive shifts increased drowsiness by 1.06 times compared to 2 shifts (8.37 events/h vs 6.77 events/h, P= 0.03). Consecutive shift sequences included afternoons (9%), mornings (29%), nights (5%), mixed rotating shifts (28%), forward-rotating shifts (11%) and backward-rotating shifts (12%). Drowsiness event rates were 1.23 times greater during night consecutive shifts relative to afternoon shifts (8.37 events/h vs 6.67 events/h, P= 0.03). Backward-rotating shifts (morning-night-evening- afternoon) elevated daytime drowsiness between 10 am and 3 pm by 1.55 times (10.01 events/h vs 6.47 events/h, P= 0.016). Conclusions Regardless of the number of consecutive shifts, sequential night shifts increase real-time drowsiness in HVDs, with backward rotating shifts resulting in higher rates of drowsiness events during daytime. The interaction of schedule features should inform the work scheduling of HVDs to reduce the risk of drowsiness.

Abstract:
Abstract Introduction Heavy vehicle drivers (HVDs), carrying approximately 75% of non-bulk domestic freight on Australian roads, are at risk of drowsiness due to night-time, long drives, or short sleep. Drowsiness comprises 46% of all driver-impairment-related factors in HVDs fatalities. However, the specific role of sleep loss in HVDs' drowsiness is less known. This study assessed the association of sleep loss, independent of other work metrics, with real-time drowsiness in HVDs. Methods Eight HVDs aged 49.8± 8 years, 27± 10.3 years of experience, worked for 3-28 (13± 6) shifts. A composite ocular measure of drowsiness (John's Drowsiness Score) and drivers' sleep-wake was monitored by Optalert glasses and Actiwatches, respectively. The drowsiness event (response variable) was defined as at least one event of JDS≥ 2.6 /h, and sleep loss (exposure) as the variation of sleep opportunity pre-shift from the 9-hour recommended rest break in Europe. Multivariate logistic regression assessed the odds of drowsiness events under sleep loss when adjusted for time of day, shift start time and hours of drive. Results Data comprised 1061 observations of work metrics or JDS and 694 records of sleep duration. Sleep loss ranged from 1 to 6.3 hours (3.4 ± 1.1h). Compared with a 1- 2.5-hour sleep loss, sleep loss&gt; 4 hours doubled the likelihood of drowsiness events when controlled for other covariates (p=0.019). Discussion Sleep loss increases the odds of drowsiness events in HVDs with similar work schedule metrics. Further research should assess if Australia's 7-h minimum break provides adequate sleep under different schedule conditions.

Abstract This paper reports on the design and construction of a High Voltage Distribution System (HVDS) for a “Smart Switch” developed to provide high voltage (HV) to a series of stacked straw detector planes in the Mu2e Electron Tracking Detector (ETD). Each plane is composed of three 120 deg. Crescent-shaped panels, and each panel is composed of 96 straw tubes. The HVDS provides HV on-off, current monitoring, recording, and crowbar for over-current protection. The inter-communication system is based on TCP/IP. The HVDS supplies HV with long term stability, and accurately monitors the applied voltage and currents.

Abstract:
Abstract Introduction Heavy vehicle drivers (HVDs) frequently experience reduced sleep due to travelling long distances under non-standard work hours. Short sleep in HVDs can increase risk of motor vehicle crashes and falling asleep while driving. This study sought to examine the influence of break duration between shifts, break onset time, and prior shift duration on HVDs’ total sleep time (TST) between consecutive work shifts, and the interaction between break duration and break onset time. Methods Twenty-seven HVDs’ sleep and shift work were monitored for up to nine weeks through actigraphy, sleep diaries, and work diaries. Differences in TST between consecutive shifts and days off were assessed. Linear mixed models and pairwise comparisons evaluated the impact of break duration, break onset time, and prior shift duration on TST between shifts. Results TST was significantly lower between consecutive shifts (M=6.38-hours) compared to days off (M=7.63-hours), p&lt;.001. Longer break durations were associated with more TST, p&lt;.001. Break durations up to 7-, 9-, and 11-hours resulted in, on average, 4.76-, 5.66-, and 6.41-hours of sleep, respectively. Breaks starting between 00:01-08:00h led to shorter TST compared to breaks starting between 16:01-20:00h, p&lt;.05. Prior shift duration and the interaction between break duration and break onset time were not associated with TST. Discussion HVDs’ TST between workdays are independently impacted by break duration and break onset time. Break durations between 7-11-hours, reflecting Australian and European break guidelines, result in insufficient sleep. Work regulations must evaluate appropriate break durations and break onset times to allow adequate sleep in HVDs.

Abstract:
Atmospheric vapor pressure deficit (VPD) is the driving force that regulates the rate of water transport within plants. Under High VPD (HVPD), plants always reduce their photosynthesis rate and close their stomata. Experiments were performed under greenhouse conditions with cucumber and tomato plants to identify the regulatory effect of VPD on plant water capacity. Treatments included two levels of soil water (100% and 60% field capacity [FC]) combined with two levels of VPD (LVPD and HVPD). Results indicated that with 60%FC, the plant heights of tomato and cucumber were enhanced under LVPD compared with those under HVPD. With 60%FC, relative leaf water contents under LVPD increased by 11% compared with those under HVPD. Furthermore, LVPD significantly improved the photosynthetic capacity of the two crops and changed their stress responses. Our results indicated that LVPD at different soil moisture levels reduced irrigation demand under greenhouse conditions. This approach can be applied in water management in greenhouse vegetable production in China and other regions of the world with temperate continental climates.

Abstract:
Background. Homonymous visual field defects (HVFDs) are one of the most common consequences of stroke. Compensatory training encourages affected individuals to develop more efficient eye movements to improve function. However, training is typically supervised, which can be time consuming and costly. Objective. To develop and evaluate the efficacy and feasibility of an unsupervised reading and exploration computer training for individuals with HVFDs. Methods. Seventy individuals with chronic HVFDs were randomly assigned to 1 of 2 groups: intervention or control. The former received 35 hours of reading and exploration training, and the latter received 35 hours of control training. Visual and attentional abilities were assessed before and after training using perimetry, visual search, reading, activities of daily living, the Test of Everyday Attention, and a Sustained Attention to Response task. Results. Eighteen individuals failed to complete the training; analyses were conducted on the remaining 28 intervention and 24 control group participants. Individuals in the intervention group demonstrated significant improvements in the primary outcomes of exploration (12.87%, 95% confidence interval [CI] = 8.44% to 17.30%) and reading (18.45%, 95% CI = 9.93% to 26.97%), which were significantly greater than those observed following the control intervention (exploration = 4.80%, 95% CI = 0.09% to 9.51%; reading = 1.95%, 95% CI = −4.78% to 8.68%). Participants in the intervention group also reported secondary subjective improvements, although these were not matched by objective gains in tasks simulating activities of daily living. Conclusions. Home-based compensatory training is an inexpensive accessible rehabilitation option for individuals with HVFDs, which can result in objective benefits in searching and reading, as well as improving quality of life.

Abstract:
Studies on Umami Taste. Preparation of Hydrolyzed Vegetable Proteins (HVPs) and Glutamate-Ribonucleotide Hybrids - ABSTRACT. Until the 1980’s, it was assumed that there were only four basic tastes: salty, sweat, sour, and bitter. It is now well recognized that a taste quality exists which is distinct from any combination of the four basic ones. This palatable fifth taste was first discovered in 1908 by K. Ikeda. He identified it as “umami”, a Japanese word that means delicious. Related terms can be savory, meaty, broth-like, mouthfilling, etc. Umami is an essential element in our appreciation of food and is imparted by monosodium L-glutamate (MSG) and 5’-ribonucleotides such as disodium inosine 5’-monophosphate (IMP) and disodium guanosine 5’-monophosphate (GMP). These compounds are now used extensively as seasonings or condiments to supplement, enhance or round-off the flavor of many savory-based processed foods. They are the best flavor enhancers that are in commercial use worldwide. The term flavor enhancer (or potentiator) is reserved for substances which have very little taste of their own but have the ability to significantly influence the taste perception of others, e.g. the components of certain types of food so that these foods become organoleptically attractive to the human palate. What is perhaps the most interesting property about MSG and 5’-ribonucleotides is their capacity to interact synergistically, i.e. the detection threshold of MSG was markedly lowered in the presence of IMP (or GMP) and vice versa. It is noteworthy that the synergistic interactions of MSG with IMP and/or GMP also occur in certain savory foods bringing about a flavor effect which is greater than the sum of the individual flavor-enhancing effects. This phenomenon of synergism is of the utmost importance, because it provides an opportunity for the food processor to use less MSG in the formulation without affecting flavor quality. For instance, it has been found that food processors who use 100 g of MSG can reduce usage levels to 17 g in the presence of 0.9 g of 50:50 blends of IMP and GMP with a substantial (25-30%) cost reduction and without an adverse effect on the organoleptic properties of the processed food. Furthermore, considering that excessive sodium intake (resulting from the traditional usage of table salt as a seasoning and a preservative agent) is believed to contribute to hypertension and the development of cardiovascular disease, it has been suggested that the low pleasantness of reduced-salt foods could be increased by addition of appropriate blends of umami flavor enhancers. Recently, the negative aura around MSG, which is accused of causing the so called Chinese restaurant syndrome, has strongly stimulated research for new umami compounds. Among them some peptides isolated from Hydrolyzed Vegetable Proteins (HVPs) have a preeminent role. HVPs are produced by chemical and/or enzymatic hydrolysis of vegetable materials rich in proteins. During this thesis we found that the mixture of peptides obtained from rice middlings and hemp seeds through enzymatic hydrolysis elicit intense glutamate-like umami taste. Such hydrolyzed vegetable proteins could then potentially be used as ingredients in culinary products. In addition, despite extensive investigations on taste receptors, the mechanisms of perception, flavor enhancement, and synergism connected with umami substances are still unclear at molecular level. To get further insight into the phenomenon of synergism, we synthesized hybrid compounds in which the umami moieties (glutamate and purine 5’-ribonucleotide) are covalently connected through flexible linkers of variable length with the aim to reach both umami receptor sites through a single molecule.

Abstract:
The presence of dirt, soil, aged polymers or corrosion patinas can hinder the readability of artworks; in these cases, non-invasive and controlled removal is essential. Nanostructured fluids (NSFs) - such as micellar solutions and microemulsions- allowed achieving this purpose, decreasing, at the same time, the drawbacks related to the use of solvents. In the last decades, several cleaning fluids have been developed; surfactants, in particular, have a crucial role in the NSFs’ formulations. For this reason, the research of innovative and highly performing amphiphiles represents one of the main goals in modern conservation science, in order to develop safer and greener systems. Two different NSFs were prepared with MPD surfactant and their interaction with soil and polymeric layers was evaluated through several techniques (CLSM, photographic observation, contact angle and surface tension measurements). Moreover, a comparison with a conventional nonionic surfactant (PDE) was made. MPD-based NSFs were found to be more effective in cleaning surfaces, also without mechanical action. Confining cleaning fluids in retentive matrices like gels represents one of the most powerful strategies to obtain greater control of the cleaning action. Two different pHEMA-based semi-IPNs were used as scaffold for a high selective agent (i.e., TEPA) able to remove corrosion products without affecting the protective cuprite layers. Changes in gels’ structure were evaluated by means DSC, TGA and SEM analysis before and after the interaction with the copper alloys; Cu(II) ion adsorption kinetics were used to assess the effect of the gels’ structure on the adsorption process. The pHEMA-based gels, classified as “rigid systems”, are not suitable for the treatment of bronze sculpture characterized by deep cavities and high reliefs. To overcome these limitations, TEPA was confined into a PVA-based film (HVPD) forming system. Thanks to its viscoelastic properties and its ability to combine a chemical action with a mechanical one, the HVPD represents a good option in these cases. The physico-chemical characterization was carried out to evaluate the effect of TEPA-addition on (1) the kinetics of the film formation, quantified through gravimetric and rheological measurements, and on (2) the final films’ properties, determined by DSC, ATR-FTIR and SEM analysis. 2D FTIR FPA Imaging confirmed the complete removal of corrosion products, the preservation of cuprite layers and the absence of residues on the mock-up surfaces after the treatment with both semi-IPNs and HVPDs. Finally, tests on real cases study are presented.

Thanks to the development of Internet of Things (IoT) technology, more and more intelligent devices are used to collect, process, and analyze data through wireless communication. Such devices can even outsource the valuable data to cloud storage, and further provide a variety of services to end-users. In this thesis, we construct a system supporting information/services delivery between pairs of vehicle-vehicle, vehicle-wireless access point, and cloud-vehicle. For pairs of vehicle-vehicle, vehicles can communicate with each other via BLE communication protocol in safety and efficiency. For pairs of vehicle-wireless access point and cloud-vehicle, they will communicate with each other by 802.11.p. Through implementing the integration system and its extensive experiments, we are confident that our system is feasible and efficient while using in practical environment.

Abstract The plasma torch design affects the particle-plasma interaction, in-flight properties and the coating microstructure. When spraying metallic powders, the in-flight oxidation as well as the particle velocity and temperature determine the mechanical, corrosion and oxidation properties, which have a major impact on the in-service degradation of bond coats. This study aims to determine the microstructural and mechanical properties of as-sprayed CoNiCrAlY coatings deposited on the Inconel 718 alloy. Depositions were made using a High Velocity Plasma Spray Process (HVPS), which is based on a special plasma torch design. In-flight particle characteristics were determined to elucidate the kinetic and thermal regime of HVPS process.

Abstract:
Abstract Mature carbonate reservoirs under waterflood in Kuwait suffer from relatively low oil recovery due to poor volumetric sweep efficiency, both areal, vertically, and microscopically. An Alkaline-Surfactant-Polymer (ASP) pilot using a regular five-spot well pattern is in progress targeting the Sabriyah Mauddud (SAMA) reservoir in pursuit of reserves growth and production sustainability. SAMA suffers from reservoir heterogeneities mainly associated with permeability contrast which may be improved with a conformance treatment to de-risk pre-mature breakthrough of water and chemical EOR agents in preparation for subsequent ASP injection and to improve reservoir contact by the injected fluids. Each of the four injection wells in the SAMA ASP pilot was treated with a chemical conformance improvement formulation. A high viscosity polymer solution (HVPS) of 200 cP was injected prior to a gelant formulation consisting of P300 polymer and X1050 crosslinker. After a shut-in period, wells were then returned to water injection. Injection of high viscosity polymer solution (HVPS) at the four injection wells showed no increase in injection pressure and occurred higher than expected injection rates. Early breakthrough of polymer was observed at SA-0561 production well from three of the four injection wells. No appreciable change in oil cut was observed. HVPS did not improve volumetric sweep efficiency based on the injection and production data. Gel treatment to improve the volumetric conformance of the four injection wells resulted in all the injection wells showing increased of injection pressure from approximately 3000 psi to 3600 psi while injecting at a constant rate of approximately 2,000 bb/day/well. Injection profiles from each of the injection well ILTs showed increased injection into lower-capacity zones and decreased injection into high-capacity zones. Inter-well tracer testing showed delayed tracer breakthrough at the center SA-0561 production well from each of the four injection wells after gel placement. SA-0561 produced average daily produced temperature increased from approximately 40°C to over 50°C. SA-0561 oil cuts increased up to almost 12% from negligible oil sheen prior to gel treatments. Gel treatment improved volumetric sweep efficiency in the SAMA SAP pilot area.
