Safeguarding water distribution systems from contamination threats using the smarttap platform

The objective of the proposed innovation project is the commercialization of the SmartTap Platform: An early-warning real-time water contamination monitoring system for the protection of water distribution systems against accidental or malicious chemical contamination events, provided as a service to utilities. Currently, water utilities rely on manual sampling to monitor water quality; however it may take days before a contamination event is detected. Competition relies on expensive sensors; as a result, most water utilities can only install such specialized sensors at very few locations within a network, thus offering reduced coverage. 

SmartTap is a cyber-physical system comprised of low-cost wireless sensory devices (physical) and smart cloud software (cyber) that are seamlessly integrated, so that the software is able to analyze the data in real-time, as well as to compensate hardware inaccuracies. The SmartTap devices monitor several physicochemical water parameters with low-cost sensors and fuse multi-sensor data at a local level to infer possible contamination events. The goal is to provide real-time water quality monitoring information to consumers and utilities and to reliably detect any contamination events within 1-2 hours, instead of days, thus significantly reducing the financial and societal impact of that event. The SmartTap Sensor System already exists as a home/industry product of Aqualligence, and is currently being field-tested by a water utility. In addition, Aqualligence provides consulting services for water security. Aqualligence envisions to offer a contamination alert service for the protection of water utilities, a very niche market which is not affected by strong competition. 

The feasibility study will present the analysis of the market segments/customer needs, the competition and the competitive advantages, the various business models and the best IP Management strategy, the risks and the financial projections under various scenarios.

Structure and mechanism of viral and cellular membrane fusion machineries

Fusion of two biological membranes is essential to life. It is required during organism development, for trafficking of material between cellular compartments, for transfer of information across synapses, and for entry of viruses into cells. Fusion must be carefully controlled and the core fusion components are typically found within a complex regulatory machine. There have been decades of research on the structure and function of individual components, on the dynamics and biophysics of fusion, and on phenotypes resulting from mutating or inhibiting component proteins. These have led to a model for fusion in which regulated refolding or assembly of proteins draws two membranes closer together until they fuse. Despite this breadth of study, we know very little about how the components of the fusion machinery function in context: How are they arranged on the membrane around the site of fusion? How do they respond structurally to regulation? How does the fully assembled machinery rearrange to reshape the membrane and drive fusion? These gaps in knowledge can be attributed to a shortage of structural biology methods able to derive structural data on proteins assembled within complex, heterogeneous or dynamic environments such as a fusion site. Here I propose to apply a combination of state-of-the-art cryo-electron tomography, image processing and correlative fluorescence and electron microscopy methods to obtain detailed structural information on assembled fusion machineries and of fusion intermediates both in vitro and in vivo. I will study how influenza virus fuses with a target membrane, complemented by studies on fusion of HIV-1 and of synaptic vesicles. By determining how viral and synaptic fusion complexes reposition and restructure prior to fusion, how they arrange around the fusion site, how they reshape the membrane to induce fusion, and how these processes can be regulated and inhibited, I will derive a mechanistic model of membrane fusion in situ.
Effect of isoquinoline alkaloids from two Hippeastrum species on in vitro acetylcholinesterase activity

The treatment of neurological disorders and neurodegenerative diseases is related to the levels of acetylcholine (ACh) through the inhibition of acetylcholinesterase (AChE). Galanthamine, an important alkaloid isolated from the Amaryllidaceae family, is approved for the pharmacological treatment of Alzheimer's disease (AD) and acts by inhibiting the acetylcholinesterase (AChE) activity. In the present study, Ellman's method was used to verify the inhibition of AChE activity of some isoquinolines alkaloids such as galanthamine, montanine, hippeastrine and pretazettine. At the concentrations 1mM, 500 microm and 100 microm, galanthamine presented an AChE inhibition higher than 90%. Montanine inhibited, in a dose-dependent manner, more than 50% of the enzyme at 1mM concentration. With the concentrations 500 microm and 100 microm, 30-45% of AChE activity inhibition was detected. The alkaloids hippeastrine and pretazettine presented no significant inhibition of the AChE activity. The results demonstrate that montanine significantly inhibits AChE activity at the tested concentrations, suggesting the necessity of further investigations on this alkaloid use in treating neurological disorders.
The biochemical roots of the RNA world: from zymonucleic acid to ribozymes.

The history of the ideas that led to the RNA World hypothesis is reviewed. As the understanding of the properties of RNA molecules progressed, the evolutionary interpretation of their genetic properties and widespread distribution in intracellular environments, as well as the catalytic properties of nucleotide coenzymes and the participation of RNA monomers in metabolic pathways, led to several independent proposals of protein-free primordial life forms. Current ideas on the RNA World are part of a long and storied scientific perspective in which these different hypotheses were developed. However, the lack of continuity between them may be explained in part by the absence of an evolutionary framework that characterized the early development of molecular biology, as well as by the demise of certain areas of research like coenzyme chemistry.

1,251,655. Cooling towers. BLAIRS Ltd. 21 Nov., 1969 [23 Aug., 1968], No. 40484/68. Heading F4K. A cooling tower has its weight supported by a main frame structure comprising vertical steel members 11 interconnected by means of horizontal steel members 15. The tower packing material, water distributing nozzles and a drift eliminator are suspended from trusses 16 extending diagonally across the top of the main frame structure. The trusses also carry a framework 17 for supporting a fan unit (not shown). Preferably the framework 17 includes a cantilever member (19, Fig. 3) to transfer some of the weight to outside the main frame structure. Glass-reinforced plastics panels 27, 28 forming an external casing are secured to framework 18 which in turn is carried by the vertical members 11. The top of the tower has plastics panels 22, 23. A water receiving pond 13 is located below the tower. The frame members 11 pass through collars 12 in the bottom of the pond into the ground at 14 so that their weight is supported independently of the pond structure.
Customer reactions to encountering consecutive service failures

According to previous studies, many consumers in Taiwan have experienced consecutive service failures. Despite these failures, many consumers still remain loyal to a service provider for a variety of reasons, such as money deposits, contractual agreements, associated costs, time constrains, and health concerns. We attempt to investigate the emotional reactions and expectations of consumers after they have experienced two consecutive service failures. Our findings reveal that for high-involvement services, although customers display strong negative emotional reactions after each service failure, the reaction to the second service failure is less intensive than that to the first one. Furthermore, our findings show that as long as the products or services remain in use, customers tend to retain high levels of expectation in regard to the service provider.

Fano photonics

A new class of devices exploiting Fano resonances and with important applications in information technology is suggested. Typically, the resonance of a system is described by a frequency and a lifetime, leading to a Lorentzian lineshape function. If the system instead involves interference between a discrete resonance and a continuum, a Fano lineshape appears with fundamentally different characteristics. Here, the Fano resonance is used to make a novel integrated mirror, enabling realization of Fano lasers, Fano switches and quantum Fano devices. These devices challenge well-accepted paradigms for photonic devices. The goals of the project are to demonstrate a laser with modulation bandwidth greatly exceeding all existing lasers; a nanolaser with linewidth three orders of magnitude smaller than existing nanocavity lasers; and a switch that operates at femtojoule energies and provides gain. Such devices are important for realizing high-speed optical interconnects and networks between and within chips. An increasing fraction of the global energy consumption is being used for data communication, and photonics operating at very high data rates with ultra-low energy per bit has been identified as a key technology to enable a sustainable growth of capacity demands. Existing device designs, however, cannot just be scaled down to reach the goals for next-generation integrated devices. The Fano mirror will also be used to demonstrate control at the single-photon level, which will enable high-quality on-demand single-photon sources, which are much demanded devices in photonic quantum technology. These devices all rely on the unique properties of the Fano mirror, which provides a new resource for ultrafast dynamic control, noise suppression and ultra-low energy operation. Using photonic crystal technology the project will achieve its goals in a concerted effort involving development of new theory, new nanofabrication techniques and advanced experiments.

IMPROVED METHOD OF MAINTAINING CONSTANT ARTERIAL PCO2 DURING INCREASED MINUTE VENTILATION AND MEASUREMENT OF ANATOMIC AND ALVEOLAR DEAD SPACE

A method is disclosed to maintain isocapnia when breathing exceeds baseline breathing and a circuit therefore. The circuit has a non rebreathing valve, a source of fresh gas, a fresh gas reservoir and a source of gas to be inhaled when minute ventilation exceeds fresh gas flow. The flow of fresh gas is equal to minute ventilation minus anatomic dead space, wherein additional inhaled gas exceeding fresh gas flow has a partial pressure of CO2 equal to the partial pressure of CO2 of arterial blood. Also disclosed is a method to identify the anatomic dead space and alveolar dead space by using a breathing circuit consisting of a non rebreathing valve, a source of fresh gas, a fresh gas reservoir and a source of gas with a partial pressure of CO2 substantially equal to that of arterial blood.
Reliability analysis of &#x201C;sibling&#x201D; components

Engineering systems often contain some identical components (parts), the so-called "siblings". In the case of an automobile, these would be engine spark plugs, light bulbs, wheels, etc. These sibling components are typically coded with the same part number. When field (warranty) data are analyzed, a dilemma arises as to how to interpret a recurrent replacement of a sibling component belonging to a given system: as a secondary failure of the component that has already been replaced once, or as the first failure of the component's sibling(s)? From the stand point of root-cause analysis, the task is to understand whether recurrent failures are related to 1) a particular sibling, which might be operating in inauspicious conditions relative to other siblings, or 2) to any other siblings on the vehicle. One could attribute Scenario 1) to a system- level (e.g., system interaction) problem, and Scenario 2) to a component-level (supplier quality) problem. This is also critical in selecting an appropriate probabilistic model for predicting the reliability of sibling components. In this paper, we propose a statistical approach that helps to resolve the above formulated dilemma.
Pleating and laminating

A method of producing a laminated, pleated fabric is provided which method comprises passing a first layer of fabric through a pleating machine to form temporary pleats and then feeding the first layer of fabric together with an adhesive material and a second layer of fabric onto a winding roller so that the adhesive layer is disposed between the first layer of fabric (which is formed with the temporary pleats) and the second layer of fabric. The three layers are substantially co-extensive in size. The adhesive material is then activated e.g. with steam or dry heat, so that the first and second layers of fabric are laminated together. The steam or heat also makes the pleats in the first layer of fabric permanent. The method can be operated as a relatively simple, continuous process to produce a laminated, pleated fabric which is visually attractive and comfortable to wear.
On the observability of bottom topography from measurements of tidal sea surface height

Abstract The question of whether features of the ocean bottom topography can be identified from measurements of water level is investigated using a simplified one-dimensional barotropic model. Because of the nonlinear dependence of the sea surface height on the water depth, a linearized analysis is performed concerning the identification of a Gaussian bump within two specific depth profiles, (1) a constant depth domain, and, (2) a constant depth domain adjoining a near-resonant continental shelf. Observability is quantified by examining the estimation error in a series of identical-twin experiments varying data density, tide wavelength, assumed (versus actual) topographic correlation scale, and friction. For measurements of sea surface height that resolve the scale of the topographic perturbation, the fractional error in the bottom topography is approximately a factor of 10 larger than the fractional error of the sea surface height. Domain-scale and shelf-scale resonances may lead to inaccurate topography estimates due to a reduction in the effective number of degrees of freedom in the dynamics, and the amplification of nonlinearity. A realizability condition for the variance of the topography error in the limit of zero bottom depth is proposed which is interpreted as a bound on the fractional error of the topography. Appropriately designed spatial covariance models partly ameliorate the negative impact of shelf-scale near-resonance, and highlight the importance of spatial covariance modeling for bottom topography estimation.
METHOD OF MANUFACTURING AN INSULATED, IMPACT RESISTANT WINDOW

An insulated glass unit (IGU) is provided. The IGU meets the industry standards for impact resistance while significantly reducing the weight of the IGU compared to conventional IGUs. In particular, the two pane IGUs of the present invention can meet or exceed industry standards for various wind storm criteria while reducing the weight and cost of the IGU. The IGU only requires one layer of film to meet the performance of previous IGU designs that require two or more layers of film laminated to two or more surfaces of glass.

Examining continuous usage of location-based services from the perspective of perceived justice

Due to the privacy risk associated with using location-based services (LBS), users are often reluctant to adopt and use them. Drawing on the justice theory, this research identified the factors affecting continuous usage of LBS. Perceived justice reflects a set of fairness perceptions and involves three dimensions: distributive justice, procedural justice and interactional justice, which reflect outcome fairness, process fairness and treatment fairness, respectively. We conducted data analysis with structural equation modeling (SEM). The results show that procedural justice is the main factor affecting privacy risk, whereas distributive justice is the main factor affecting perceived usefulness. Privacy risk and perceived usefulness influence continuous usage. Thus mobile service providers need to improve users' perceived justice to facilitate their usage of LBS.
High proportion of mosquito vectors in Zika forest, Uganda, feeding on humans has implications for the spread of new arbovirus pathogens

There is a steady increase in the contact between humans and wildlife, brought about by encroachment, destruction of natural forests, climatic and environmental changes. Mosquitoes get exposed to hosts and pathogens; creating possibilities for new disease patterns. Therefore, the identification of blood-meal sources is important to determine the linkages between hosts and vectors. Engorged mosquitoes were collected in Zika forest (Uganda) for a period of 12 months using carbon dioxide (CO2)-baited light traps. Total genomic DNA was extracted from the abdominal contents of the mosquitoes and the diagnostic regions of the mitochondrial genes, cytochrome oxidase subunit 1 (COI) and cytochrome b (cytb) sequenced. The sequences were subsequently blasted in the GenBank. Sequence analyses revealed that feeds were derived from mammalian and avian hosts. Blood-meal sources from Aedes africanus (Theobold) examined were entirely human. There were significant differences between host species from which the mosquito species fed (Krusakal Wallis test, χ2 = 19.118, df = 5, p = 0.018). Several mosquitoes were considered as potential bridge vectors for a number of arboviruses and other diseases have been collected from the forest. Taking of mammalian origin blood-meals, including humans, may facilitate exposure to new pathogens and disease patterns.

Improvements in frictional bodies for clutches and the like and in the method of making the same

267,961. Kirchbach'sche Werke Kirchbach &. Co. March 17, 1926, [Convention date]. Cone and disc. - The frictional elements of clutches, brakes, &c. are made by applying plastic friction material in large masses to perforated annular carrier discs and forcing it into the pertorations. A steel disc 2, Fig. 1, is provided with circular or other holes 1. which may be undercut, and the material 3, consisting of fibres, such as asbestos, cotton, hemp, brass wires, or any mixtures thereof, or, a wover fabric, bonded by "Bakelite," synthetic resin, or other binding-agent, is applied in a continuous layer to each side of the disc, the two layers being united at the perforations by pressure, The facings are hardened under pressure by heat, and are then ground. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification, in which separate sector-shaped pieces 14, 14a, Figs. 4 and 7 (Cancelled), are so applied to both sides of an annular disc 11 as to form practically coutinuous surfaces. The disc 11 has groups of round-edged holes 12, 13, the larger central hole 13 of each group receiving a long projection 16 on the piece 14, while the holes 12 receive short projections 15, 15<a> on the pieces 14, 14<a> respectively. Under pressure, the projections 15, 15<a> are united midway in the holes 12, the projection 16 being received in a bore of the piece 14a. Before application of the facings, they and the carrier disc are preferably coated with the binding-agent. Instead of passing to the middle of the thickness of the disc, the projections 15, 15<a> may alternately pass completely through the disc. This subject-matter does not appear in the Specification as accepted.
