Washed vegetative cells of Bacillus mycoides obtained and treated under specified conditions have been found to sporulate when shaken in distilled water under specified conditions. Within limitations of the methods, a heat-resistant cell (spore) is produced for each heat-sensitive vegetative cell present initially. Several different experiments designed to detect massive lysis and cell growth d...

models in general use. While the weight of a pair of Anderson's forceps is about 1 lb. 10 ozs. the " Bengal forceps " weighs only a pound. In the " Bengal forceps " pelvic curves are a little more pronounced than usual and the distance between the shanks near the joint is wide enough to admit the forefinger. The handles are made like those of amputation knives, and give an efficient hold withou...

This paper describes Jal, the new AUV designed by the student team of IURS for the purpose of shallow water survey, analysis and pipeline repair and monitoring operations. Propelled by two lateral and vertical propulsion thrusters, Jal weighs only about 7 Kg and measures close to 0.45 m in length and 0.36 m in width & height. Onboard sensor systems, custom passive sonar, real-time computer visi...

The newest introduction to echocardiography is a hand-carried ultrasound (HCU) device. It is a small echocardiographic machine that typically weighs less than 6 lb and can obtain echocardiographic images and data. However, neither the device nor the context of the examination fulfills the criteria for a comprehensive or complete echocardiographic examination. The American Society of Echocardiog...

This paper presents the design of the 'Tree Hugger', an open access, transportable, 1.1 MHz (1)H nuclear magnetic resonance imaging system for the in situ analysis of living trees in the forest. A unique construction employing NdFeB blocks embedded in a reinforced carbon fibre frame is used to achieve access up to 210 mm and to allow the magnet to be transported. The magnet weighs 55 kg. The fe...

We offer a new metric for big data platforms, COST, or the Configuration that Outperforms a Single Thread. The COST of a given platform for a given problem is the hardware configuration required before the platform outperforms a competent single-threaded implementation. COST weighs a system’s scalability against the overheads introduced by the system, and indicates the actual performance gains ...

The spleen (from Greek: splen; Latin: lien) has the shape of a coffee bean, weighs about 150 grams, and is located in the left posterior upper abdomen (epigastric region). Next to such large topics as heart, liver, or lung, the spleen is sometimes a bit neglected in the curriculum; therefore, many students struggle in exams when it comes to questions about the ligaments or blood circulation of ...

We propose a new filter called Bi-affinity filter for color images. This filter is similar in structure to the bilateral filter. The proposed filter is based on the color line model, which does not require the explicit conversion of the RGB values to perception based spaces such as CIELAB. The bi-affinity filter measures the affinity of a pixel to a small neighborhood around it and weighs the f...

In this paper, we present the design and development of the UC-Softhand. The UC Softhand is a low cost, Bionic and adaptive hand that takes advantage of compliant joints. By optimization of the actuation strategy as well as the actuation mechanism, we could develop an anthropomorphic hand that embeds three actuators, transmission mechanisms, controllers and drivers in the palm of the hand, and ...

Optimal climate policy is studied in a Ramsey growth model. A developing economy weighs global warming less, hence is more likely to exhaust fossil fuel and exacerbate global warming. The optimal carbon tax is higher for a developed economy. We analyze the optimal time of transition from fossil fuel to renewables, amount of fossil fuel to leave in situ, and carbon tax. Subsidizing a backstop wi...
