Scriber for silicon wafers
A device for dividing silicon wafers into rectangular chips is characterized by a base including a horizontally oriented bed with a planar support surface, a vacuum chuck adapted to capture a silicon wafer seated on the support for translation in mutually perpendicular directions. A stylus support mounted on the bed includes a shaft disposed above and extended across the bed and a truck mounted on the shaft and supported thereby for linear translation along a path extended across the bed a vertically oriented scribe has a diamond tip supported by the truck also adapted as to engage a silicon wafer captured by the chuck and positioned beneath it in order to form score lines in the surface of the wafer as linear translation is imparted to the truck. A chuck positioning means is mounted on the base and is connected to the chuck for positioning the chuck relative to the stylus

Primer on adult patient satisfaction in perioperative settings.
The topic of patient satisfaction has gained increasing importance over the past decade. Due to the impact of patient satisfaction on health care quality, understanding factors that predict satisfaction is vital. The purpose of this review is to examine the literature and identify factors related to patient perioperative satisfaction as well as predictive variables that, if modified, can enhance satisfaction scores of patients undergoing surgery. Our review reports that patient satisfaction scores are affected by modifiable factors such as clinician-patient communication, information provision to patients, and operational function of a hospital. Non-modifiable factors affecting patient satisfaction scores include patient demographics such as gender, age, and education. In order to enhance patient perioperative satisfaction, we suggest that anesthesiologists and surgeons focus their efforts on enhancing their communication skills and providing information that is appropriately tailored to the understanding of their patients
Crescent City Nightingales: Gender, Race, Class and the Professionalization of Nursing for Women in New Orleans, Louisiana, 1881-1950
Through the examination of primary sources largely overlooked by historians, this dissertation traces the professionalization of nursing in New Orleans, Louisiana, from 1881 to 1950 while placing this localized history within the context of national trends. In the late nineteenth century, nursing developed into a middle class profession for women inspired by the careers of Florence Nightingale and Clara Barton. This dissertation investigates the process by which women became professional nurses while a complex intersection of issues related to gender, race, and class at times advanced, and at other times, hindered their progress towards professionalization. New Orleans serves as a useful case study to illustrate the progression of nursing in both location and time. The city’s subtropical climate and position as a major port of immigration fostered an array of natural and public health disasters that offered an opportunity for the development of professional nursing. Partnerships among male hospital administrators, Catholic Sisters, and upper class clubwomen in New Orleans led to the establishment of seven professional schools, six for whites and one for blacks, that offered specialized nursing education to women of all social classes. When disasters struck New Orleans and elsewhere, nursing for the American Red Cross demanded biracial cooperation for relief work. After the American Red Cross shifted its national mission to war relief and entered into a tenuous partnership with the military, nurses from New Orleans served around the world and at home. Disasters and wars had created opportunities for nurses to earn public recognition and trust and expand control over their careers. Their service in the military particularly influenced federal legislation that raised their status and authority and lifted restrictions on gender and race

Behind the Banner of Patriotism: The New Orleans Chapter of the American Red Cross and Auxiliary Branches 6 and 11 (1914-1917)
Socialite Laura Penrose and a group of wealthy businessmen founded the New Orleans Chapter of the American Red Cross in 1916. The Chapter expanded in 1917 with the addition of two black Auxiliary Branches chartered by nurses Louise Ross and Sarah Brown. Although Jim Crow dictated the division between the Chapter and its Branches within the mostly female organization, racial barriers did not prohibit them from uniting for the cause of national relief. The American Red Cross differed from other forms of biracial Progressivism by the very nature of public relief work for a national charity. American Red Cross relief work brought women into public spaces for the war effort and pushed biracial cooperation between women in the Jim Crow South in a more public and patriotic direction than earlier efforts at social reform. Black women, in particular, used the benefit of relief work to promote racial uplift and stake a claim on American citizenship despite the disenfranchisement of their men
Oligarchic planetesimal accretion and giant planet formation II
The equation of state calculated by Saumon and collaborators has been adopted
in most core-accretion simulations of giant-planet formation performed to date.
Since some minor errors have been found in their original paper, we present
revised simulations of giant-planet formation that considers a corrected
equation of state. We employ the same code as Fortier and collaborators in
repeating our previous simulations of the formation of Jupiter. Although the
general conclusions of Fortier and collaborators remain valid, we obtain
significantly lower core masses and shorter formation times in all cases
considered. The minor errors in the previously published equation of state have
been shown to affect directly the adiabatic gradient and the specific heat,
causing an overestimation of both the core masses and formation times.Comment: 4 pages, 2 figures, Accepted for publication in Astronomy and

The Saco River Plume: A Discussion Of The Near-Field Dynamics
This study focused on the freshwater discharge plume from the Saco River in southwestern Maine to determine the mechanisms responsible for the largest impacts on the near-field dynamics in this region. We examined the forcing factors that tended to increase the plume\u27s spatial extent upshelf of the river mouth. Salinity, temperature, and density data were collected during cruises from May through November 2010 and by two surface moorings deployed upshelf of the Saco River mouth. We found a distinct variation in the latitude of the upshelf boundary of the plume during and after periods of high discharge. Furthermore, we found that the upshelf boundary of the plume responds to northeastward winds by thinning and moving further upshelf of the Saco River mouth and to southwestward winds by deepening and moving closer to the point of discharge. These movements can affect coastal ocean salinity levels and result in the transport of suspended pollutants and other materials to areas some distance from the point of discharge, causing harmful effects
CHEOPS performance for exomoons: The detectability of exomoons by using optimal decision algorithm
Many attempts have already been made for detecting exomoons around transiting
exoplanets but the first confirmed discovery is still pending. The experience
that have been gathered so far allow us to better optimize future space
telescopes for this challenge, already during the development phase. In this
paper we focus on the forthcoming CHaraterising ExOPlanet Satellite
(CHEOPS),describing an optimized decision algorithm with step-by-step
evaluation, and calculating the number of required transits for an exomoon
detection for various planet-moon configurations that can be observable by
CHEOPS. We explore the most efficient way for such an observation which
minimizes the cost in observing time. Our study is based on PTV observations
(photocentric transit timing variation, Szab\'o et al. 2006) in simulated
CHEOPS data, but the recipe does not depend on the actual detection method, and
it can be substituted with e.g. the photodynamical method for later
applications. Using the current state-of-the-art level simulation of CHEOPS
data we analyzed transit observation sets for different star-planet-moon
configurations and performed a bootstrap analysis to determine their detection
statistics. We have found that the detection limit is around an Earth-sized
moon. In the case of favorable spatial configurations, systems with at least
such a large moon and with at least Neptune-sized planet, 80\% detection chance
requires at least 5-6 transit observations on average. There is also non-zero
chance in the case of smaller moons, but the detection statistics deteriorates
rapidly, while the necessary transit measurements increase fast. (abridged)Comment: 32 pages, 14 figures, accepted for publication in PAS
