The introduction of electrically charged sprays in agricultural application has become inevitable for better control on droplet transference with reduced drift with less spray chemical requirements.  The study was under taken to develop an electrostatic induction spray charging system as attachment to knapsack mist-blower. A high voltage generator was fabricated on the basis of Cockcroft-Walton voltage multiplier principle with input of 6 V DC battery. A self-atomizing hydraulic nozzle was developed to deliver the droplet spectrum required for effective electrostatic charge induction.  The prototype was evaluated for charge to mass ratio (mC. kg-1) at five electrode potentials (1 kV, 2 kV, 3 kV, 4 kV and 5 kV) at four electrode placement positions from atomization zone (0, 5, 10 and 15 mm). The charge mass ratio (CMR) value of spray cloud was measured using Faradays Cage at five positions from nozle tip (50, 100, 150, 200 and 250 cm). The electrode voltage potential at 5 kV at its position 5 mm from the atomization zone shown the maximum CMR value of 1.088 mC.kg-1. In contrast with commercial system (ESS-MBP90) it was observed that except at 50 cm distance, the developed charging system, at 4 kV and 5 kV, surpassed commercial system in CMR from 100 cm to 250 cm distances. The droplet spectrum of the developed system was analysed and observed that the size of droplets were 100 to 200 µm.  The developed system found to be cost effective and significantly consistent over the commercial one.

Fire Stations

Recent advancements of electric vertical take-off and landing (eVTOL) aircraft have generated significant interest within and beyond the traditional aviation industry, and many novel applications have been identified and are in development. One promising application for these innovative systems is in firefighting, with eVTOL aircraft complementing current firefighting capabilities to help save lives and reduce fire-induced damages. With increased global occurrences and scales of wildfires—not to mention the issues firefighters face during urban and rural firefighting operations daily—eVTOL technology could offer timely, on-demand, and potentially cost-effective aerial mobility capabilities to counter these challenges. Early detection and suppression of wildfires could prevent many fires from becoming large-scale disasters. eVTOL aircraft may not have the capacity of larger aerial assets for firefighting, but targeted suppression, potentially in swarm operations, could be valuable. Most importantly, on-demand aerial extraction of firefighters can be a crucial benefit during wildfire control operations. Aerial firefighter dispatch from local fire stations or vertiports can result in more effective operations, and targeted aerial fire suppression and civilian extraction from high-rise buildings could enhance capabilities significantly. There are some challenges that need to be addressed before the identified capabilities and benefits are realized at scale, including the development of firefighting-specific eVTOL vehicles; sense and avoid capabilities in complex, smoke-inhibited environments; autonomous and remote operating capabilities; charging system compatibility and availability; operator and controller training; dynamic airspace management; and vehicle/fleet logistics and support. Acceptance from both the first-responder community and the general public is also critical for the successful implementation of these new capabilities. The purpose of this report is to identify the benefits and challenges of implementation, as well as some of the potential solutions. Based on the rapid development progress of eVTOL aircraft and infrastructures with proactive community engagement, it is envisioned that these challenges can be addressed soon. NOTE: SAE EDGE™ Research Reports are intended to identify and illuminate key issues in emerging, but still unsettled, technologies of interest to the mobility industry. The goal of SAE EDGE™ Research Reports is to stimulate discussion and work in the hope of promoting and speeding resolution of identified issues. These reports are not intended to resolve the challenges they identify or close any topic to further scrutiny.

The introduction of electrically charged sprays in the agricultural application has become inevitable for better control on droplet transference with reduced drift and an increase in application efficiency with less spray chemical requirements. The present study was undertaken to develop an electrostatic induction spray charging system as an attachment to powered knapsack mist-blower. A high voltage generator was fabricated on the basis of the Cockcroft-Walton voltage multiplier principle with the input of 6 V DC battery to provide the high voltage required at the developed charging electrode assembly (Model III, Model IV and Model V) for inducing an electrostatic charge on spray droplets. The three prototypes (III, IV, and V) were evaluated for charge to mass ratio (mC.kg-1) at five electrode potentials (1 kV, 2 kV, 3 kV, 4 kV, and 5 kV), four electrode placement positions (0 mm, 5 mm, 10 mm and 15 mm) and five distances (50 cm, 100 cm, 150 cm, 200 cm, and 250 cm) from the nozzle. Model V with electrode voltage potential at 5 kV and EPP at 5 mm shown the maximum CMR value (1.088 mC.kg-1), followed by Model III (0.888 mC.kg-1) and Model IV (0.777 mC.kg-1) with similar combination of variables. In contrast with a commercial system (ESS-MBP90) it was observed that except at 50 cm distance from the nozzle, Model V (at 4 kV and 5 kV) surpassed the commercial system in CMR from 100 cm to 250 cm distance. The droplet spectrum of the developed system was analyzed and observed that the size of droplets was 100 to 200 µm. The deposition efficiency of the developed system was on par with that commercial unit and was within the range of 60 to 70 percent. The developed system found to be cost-effective and significantly consistent on par with the commercial system.

Gynecologic Neoplasms

The female reproductive tract may be the site of a wide variety of benign and malignant tumors, as well as non-neoplastic tumor-like conditions, most of which can be diagnosed by light microscopic examination including special stains and more recently immunoperoxidase techniques. Nevertheless there are situations where ultrastructural examination can contribute substantially to an accurate and specific diagnosis. It is my opinion that electron microscopy can be of greatest benefit and is most cost effective when applied in conjunction with other methodologies. Thus, I have developed an approach which has proved useful for me and may have benefit for others. In cases where it is deemed of potential value, glutaraldehyde-fixed material is obtained at the time of frozen section or otherwise at operation. Coordination with the gynecologic oncologist is required in the latter situation. This material is processed and blocked and is available if a future need arises.

Ibm Pc

IBM PC compatible computers are widely used in microscopy for applications ranging from control to image acquisition and analysis. The choice of IBM-PC based systems over competing computer platforms can be based on technical merit alone or on a number of factors relating to economics, availability of peripherals, management dictum, or simple personal preference.IBM-PC got a strong “head start” by first dominating clerical, document processing and financial applications. The use of these computers spilled into the laboratory where the DOS based IBM-PC replaced mini-computers. Compared to minicomputer, the PC provided a more for cost-effective platform for applications in numerical analysis, engineering and design, instrument control, image acquisition and image processing. In addition, the sitewide use of a common PC platform could reduce the cost of training and support services relative to cases where many different computer platforms were used. This could be especially true for the microscopists who must use computers in both the laboratory and the office.

Abstract Using the iPad tablet for Augmentative and Alternative Communication (AAC) purposes can facilitate many communicative needs, is cost-effective, and is socially acceptable. Many individuals with communication difficulties can use iPad applications (apps) to augment communication, provide an alternative form of communication, or target receptive and expressive language goals. In this paper, we will review a collection of iPad apps that can be used to address a variety of receptive and expressive communication needs. Based on recommendations from Gosnell, Costello, and Shane (2011), we describe the features of 21 apps that can serve as a reference guide for speech-language pathologists. We systematically identified 21 apps that use symbols only, symbols and text-to-speech, and text-to-speech only. We provide descriptions of the purpose of each app, along with the following feature descriptions: speech settings, representation, display, feedback features, rate enhancement, access, motor competencies, and cost. In this review, we describe these apps and how individuals with complex communication needs can use them for a variety of communication purposes and to target a variety of treatment goals. We present information in a user-friendly table format that clinicians can use as a reference guide.
